Question

5.
Consider the following statements:
1. Half life period of first order reaction is directly
proportional to the initial concentration of
reactants.
2. A catalyst increases the rate of a reaction by
lowering its activation energy.
3. A zero order reaction takes finite time for
completion while the first order reaction would
get completed in infinite time,
islare core?​

Answer 1

Answer:

please please please tell me

Answer 2

Answer:

(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.
