Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate

ENVIRONMENTAL FACTORS External environmental factors include sociocultural‚ Legal‚ Economic‚ Political‚ and Technology. The micro environment on the other hand comprises the industry and market. SOCIOCULTURAL FACTORS. Religion‚ education‚ ethnicity‚ education and language‚ age group‚ family‚ cross cultural differences. In 1978‚ the Chinese government introduced a birth control policy of one child per family. (Newsweek 2014) This in the long run will reduce both sales and labor availability

Diffusion of Ammonium hydroxide with red litmus paper Definition of diffusion 1. Diffusion is the process in which particles move from an area of high concentration to an area of low concentration in order to evenly spread out. 2 Diagram. 3. During the diffusion tube experiment I noted that firstly ammonium hydroxide was placed on to a piece of cotton wool. The cotton wool (with the ammonium hydroxide) was then placed in to a diffusion tube containing around 10 pieces of curled red

Diffusion And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion. In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells

Investigating Factors That Affect Rates Of Reaction Aim: How does the mass of calcium carbonate affect its rate of reaction with hydrochloric acid? Hypothesis: I hypothesize that when the mass of the calcium carbonate increases‚ the rate of reaction of the calcium carbonate and hydrochloric will also increase. The collision theory states that the more successful collisions there are within the reaction‚ the faster the rate of reaction. When the mass increases‚ so does the number of particles

This paper begins with how Verizon can use environmental scanning to gain a competitive advantage in the marketplace. Then‚ the paper examines how Verizon can analyze its remote‚ industry and external operating environments. External environments are the legal‚ social‚ economic‚ and political factors. Communication provider use its resources to provide greater value. Resources are critical to a company’s strategy this helps a company create and sustain an advantage over competitors. Evaluating the

Simple Diffusion Activity 1: Simulating Simple diffusion 1. What is the molecular weight of Na+? 22.99 or 23 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through?50‚100‚ 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin was too large to diffuse into the right beaker. Activity 2: Simulating Dialysis 6. What happens to the urea concentration

hot for the cell to handle‚ it breaks up or ’melts’‚ releasing what was inside of the cell. This is shown by the results in the graph by the lower temperature not showing much pigment diffused into the water and there being a lot of pigment in the water diffused at a higher temperature. Temperature can also affect the rate of diffusion because a higher temperature will cause molecules to move faster and increase the rate of diffusion‚ allowing more pigment to pass through the membrane‚ in the 5 minutes

Environmental Factors of International Business By Walter Johnson‚ eHow Contributor Environmental factors for international business comprise the external relations a firm will face in going global. These include‚ most importantly‚ the economic‚ political and legal environments‚ each of these always entangled with the others. Basic Issues The central issues for the decision to go global are concerned with minimizing risk. A company‚ when considering the environment that it will deal with when entering
