at how the concentration of acid can change the reaction and how I can explain this using collision theory. My Prediction: I predict that the greater amount of concentration the faster the reaction will take place. Therefore‚ particles in the two compounds will collide faster. Due to my prediction if it is correct‚ I expect to see the cross on the paper disappear faster. As I already know that increasing one quantity will speed up the reaction as the particles are more likely to collide.

Consecutive Reaction: The Reduction of Cr(VI) by Glutathione By: Hector Sepulveda ID:900105300 University of Texas at the Permian Basin Abstract In the experiment the reduction of Cr(VI) by glutathione will be monitored‚ the data will be recorded and the double-exponential dependence of the reaction will be analyzed. Exponential stripping‚ as well as computer assisted non-linear regression analysis will be utilized to determine the rate equation as well as the rate constants of the reaction. Introduction

The Kinetics of α-Chymotrypsin Introduction Chymotrypsin is a protease which cleaves proteins by a hydrolysis reaction‚ it does this by adding a molecule of water to a peptide bond. Although the hydrolysis reaction is thermodynamically favoured in the absence of a catalyst the half-life for a typical hydrolysis reaction by a protease is between 10 and 100 years‚ needless to say it is extremely slow1. Though this is true peptide bonds are hydrolysed within milliseconds in the body in the presence

would appear as if the reaction has stopped‚ but in fact‚ the rates of the forward and reverse reactions are equal‚ causing the reactants and products to be created at the same rate. This can be expressed mathematically in the form of the equilibrium constant. The following is the general equation for a reversible chemical reaction: aA+bB →cC+dD Equation 1 Equation 2 below will give the equilibrium constant‚ Keq‚ for this general reaction‚ where the square brackets

Concentration Dependence of Reaction Rates Introduction: The purpose of this experiment was to determine the differential rate law for a chemical reaction based on the relationship between the concentration of reactants and the rate of reaction. Since spectrophotometers‚ like Spec-20s‚ provide information about concentration‚ these instruments were used to monitor the increase or decrease in concentration of a reactant in a solution over time. By plotting [phph2-] versus time and changing the concentration

in rate is only due to the change in concentration of A (Propanone). The concentration of propanone in experiment 2 is the double of it in experiment 1. Something similar happens with the rate: In experiment 2 the rate is almost the double than the rate of experiment 1. This means that the order of [C3H6O] is 1. 2) In experiment 4 and 5 [Solution B] is the only one which changes. The concentration of iodine in experiment 5 is the half than in experiment 4. It is noticeable that the rate didn’t
