Question

The rate of any chemical reaction is directly proportional to molar concentration.

• A. True
• B. False

Answer 1

The correct option is B False

The given statement is false.
The rate of first order chemical reaction is directly proportional to molar concentration.
Rate $=k\left[A\right]$
The rate of second chemical reaction is directly proportional to molar concentration of two reactants or square of molar concentration of one reactant.
Rate $=k\left[A\right]\left[B\right]$
Rate $=k[A{]}^2$
