WebApr 11, 2024 · Temperatures beyond the optimum denature most enzymes. The concentration of the chemical reactants also affects the rate of reaction by altering the number of reacting molecules. A higher concentration increases the number of molecules available for collision. This increases the rate of collision and hence the rate of reaction. WebThe rate determining step is important in deriving the rate equation of a chemical reaction. For example, consider a multi-step reaction: (3.5.1) A + B → C + D Assume the elementary steps for this reaction are the following: Step 1: Slow A + A → C + E (with a rate constant, k 1) Step 2: Fast E + B → A + D (with a rate constant, k 2) WebMany reactions, especially those that take place in solution, occur too rapidly to follow by flow techniques, and can therefore only be observed when they are already at equilibrium.
