concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that react

interest rates As a result of our current economic situation‚ the bank is contemplating lowering interest rates to a monumental level. They are suggesting we make them negative. This would mean it would cost money to save money; the intention behind this is to stimulate spending within the economy. If businesses are forced to spend more money‚ then aggregate demand shifts to the right as investment‚ one of the components of AD‚ has been increased. Although‚ the interest rate isn’t simply one rate it

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

November 04‚ 2012 Running Head: Turnover Rate in Corrections Abstract Throughout the years‚ there has been one major dilemma that continues to hassle the administration whose sole purpose is to provide institutional sanctions‚ treatment programs‚ and services for managing criminal offenders. This dilemma is the high turnover rate of the Corrections Officers‚ whom agencies nation wide are losing at an extremely high rate. Recent statistics indicate that nearly half of

Internal Rate of Return In investment decision analysis you may need to calculate internal rate of return. “Internal rate of return (IRR) is the discount rate that gives the project a zero NPV” (McLaney‚ 2006). It is a good choice to use for investment projects. There is a formula for the internal rate of return: (A is the lower discount rate and B is the higher rate‚ a is the NPV at the lower rate and b is the NPV at the higher rate.) For example the Net Present Value (NPV) is 88 when the

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

representation‚ which more clearly displays the relationship‚ view Figure 2. The rate at which the reaction occurred for the 100% concentration is 1.45 mg/dL per minute. For the 50%‚ the rate was 3.05 mg/dL per minute‚ and for the 25%‚ the rate was 2.76 mg/dL per minute. As seen‚ the rate fluctuated from the lowest rate at 100% and the greatest rate occurring at 50%. As mentioned earlier‚ the Collision Theory states the rate of a chemical reaction is proportional to the number of collisions that occur
