Solution

The correct option is A 1, 3 and 4 arc corrcet
(1) The rate of reaction is directly proportional to the concentration of the reactant.
(2) Its half-life period is not constant. It changes from substance to substance.
(3) Concentration of reactant falls exponentially.
(4) It has low activation energy of these statements.
So statements 1,3 and 4 are correct.
