    Investigation: Reaction Time Ruler Test Date: Name: Partners Name(s): Marks: /22 (Group) + /18 (Individual) = /40 Introduction: Reaction time is the time between the application of a stimulus and the body’s response to the stimulus. Reaction time is quickest for young adults and gradually slows down with age. Reaction time can be improved with practice‚ up to a point‚ and it declines under conditions

    Two-way reactions continue until equalibrium (the state at which there is balance between reactants and products) is reached. Discovering the equilibrium constant for a reaction is very helpful for understanding that reaction. Knowing the equilibrium constant of a reaction is important because it allows you to calculate how much product will ultimately be formed during a reaction. Moreover‚ it also tells you how a particular mixture of chemicals will react. This is because chemical reactions always

    Chemical Reaction:- The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance. (b) Change of colour of substance

    Changing the Rate of Reaction PART 1: PARTICLE SIZE Question: How does changing the particle size of marble (CaCO3) affect the rate of reaction when it is added to hydrochloric acid (HCl)? Hypothesis: If I change the particle size of marble to test how to change the rate of a chemical reaction‚ than the chemical reaction with the smallest marble particles will produce CO2 the quickest because the larger the surface area‚ the more place the hydrochloric acid will have to collide with the marble

    Diels-Alder cycloaddition reaction was discovered by Otto Diels and Kurt Alder and is very useful in the synthesis of polycyclic compounds. The Diels-Alder reaction can be described as: [4+2] cycloaddition- a diene with 4 π electrons + 2π electrons from the dienophile; a pericyclic concerted reaction- meaning the reaction occurs in a single step (no intermediates) and involves a cyclic redistribution of bonding electrons. In order for a Diels-Alder reaction to take place the diene must

    Kinetics of an SN1 reaction: the effect of solvent on rate Object The purpose of this experiment is to determine the rate of hydrolysis in acetone/water (50/50 v/v and 60/40 v/v). Background and Theory An SN1 reaction of tert-butyl chloride takes place in two steps. First‚ the Alkyl Halide will leave the molecule. In this step the bond is breaking‚ which takes a longer amount of time‚ so it will determine the rate of the reaction. As a result‚ it forms a tertiary carbocation‚ since this

    together by ionic bonds in a lattice shaped structured. They are packed tightly together to maximize the attraction between the ions. When two compounds are mixed together‚ they form a precipitate. A precipitate is solid that is formed from a chemical reaction. A cation is a positively charged ion and an anion is a negatively charged ion. Hypothesis: The anion and the cation will react to form a precipitate more often than not.
