Question

Under a given set of experimental conditions, with increase in the concentration of the reactants, the rate of a chemical reaction________for positive order reactions.

• A. Decreases
• B. Increases
• C. Remains unaltered
• D. First fecreases and then increases

Answer 1

The correct option is B Increases

Under a given set of experimental conditions, with an increase in the concentration of the reactants the rate of a chemical reaction increases.
rate $=k[A{]}^n$
However, this is not true for a zero-order reaction as the rate of the reaction is independent of concentration.
rate $k[A{]}^0$
