Question

Under a given set of experimental conditions , with increase in the concentration of the reactants , the rate of a chemical reaction.

• A. Decreases
• B. Increases
• C. Remains unaltered
• D. First decreases 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.
$rate=k[A{]}^0$
