Question

Which of the following statements is correct (for zero order reaction)?

• A. The rate of a reaction decreases with passage of time as the concentration of reactants decreases.
• B. The rate of a reaction is same at any time during the reaction.
• C. The rate of a reaction is independent of temperature change.
• D. The rate of a reaction decreases with increase in concentration of reactant(s).

Answer 1

The correct option is A The rate of a reaction decreases with passage of time as the concentration of reactants decreases.

In a $zero$ order reaction , $t_{\frac{1}{2}}\propto a$

Half time time period is proportional to the initial concentration.

And Rate of reaction decreases with decrease in concentration.
