RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

GENDER BIAS AMONG NURSES Gender bias is common in nursing. It is my own experience of facing gender bias in my own institution. When I was working as an Instructor in my institution‚ there was opportunity to for me to get promotion but was denied and it was given to a female colleague. As I was working there for last three years with an out standing performance for all those years in my opinion and that of many others‚ it was my right to promoted to that post. But the head of my institute had promoted

Paper #2- Representativeness Bias Throughout the meeting and hiring process‚ the selection of capable candidates frequently relies on producing a decision using intuitive judgment. Using heuristics in employee selection requires applying your common sense to select the top individual for the occupation‚ while sticking to local‚ state and federal rules for employment. Some companies employ hiring managers that have a little bit of a different idea on who to choose to hire. A large pool of all

Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when

IQ TEST RESEARCH A Research of the Reliability and Validity of the PSYGAT on Different Linguistic Backgrounds Abstract The issue of cultural bias in intelligence tests sparks debates every time the latter is created or administered‚ resulting to many researches into how the reliability and validity of an ability test may differ when assessed on groups from different cultural-linguistic backgrounds. The aim of this study is to test the reliability and validity of the PSYGAT Verbal IQ Test on

PSY150 UNDERSTANDING SOCIAL BEHAVIOR TERM PROJECT Concept 1. Actor Observer Bias (Chapter 2) Actor observer bias is a type of bias in attribution process. In actor observer bias‚ people tend to interpret and react the same situation in different ways because of the position that they are in. As a result‚ they -as actors and observers- make different statements about the same situation. In fact‚ if a person is in the actor position‚ the attributions that s/he makes are based on the external factors

Outgroup Homogeneity Bias Outgroup Homogeneity Bias is: “the assumption that outgroup members are more similar to one another than ingroup members are to one another.” So in saying that your group (two or more people that have the same interests‚ traits or goals) are different people with different lives and traits while the people that are in the outgroup (anyone that is not in your group) are all the same and can be categorized and described the same way. With this definition

Abstract “Reaction Time” is the interval of time between the application of a stimulus and the detection of a response and has been thought to differ based upon the effects of modality and warning signals. In the “Reaction Time” experiment a total of 24 students from the University of Cincinnati participated in an experiment consisting of two sensory modalities‚ audition and vision‚ which were combined with two levels of warning signal status. The two levels of warning signal status were signal
