Zero-order reactions do not depend upon the concentration of _.
Correct answer: B. Initial Conc of Reactants
- A. Initial Conc of Products
- B. Initial Conc of Reactants
- C. Ions
- D. Radicals
Explanation
Zero-order reactions are unique because their reaction rate remains constant and does not depend on the concentration of reactants. This means that even if the concentration of reactants decreases, the rate of reaction remains unchanged until the reactants are exhausted. Therefore, option B is correct as it identifies that the rate does not depend on the initial concentration of reactants. Option A is incorrect because products do not affect the rate of zero-order reactions. Options C and D are also incorrect as they pertain to ions and radicals, which do not influence the rate of zero-order reactions, emphasizing the independence from reactant concentration.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
