For a first order reaction $$A\left( g \right) \to 2B\left( g \right) + C\left( g \right)$$ at constant volume and $$300K,$$ the total pressure at the beginning $$(t=0)$$ and at time $$t$$ are $${P_0}$$ and $${P_1},$$ respectively. Initially, only $$A$$ is present with concentration $${\left[ A \right]_0},$$ and $${t_{1/3}}$$ is the time required for the partial pressure of $$A$$ to reach $$1/{3^{rd}}$$ of its initial value. The correct option(s) is (are) (Assume that all these gases behave as ideal gases)

In a bimolecular reaction, the steric factor $$P$$ was experimentally determined to be $$4.5.$$ The correct option(s) among the following is (are)
A
The activation energy of the reaction is unaffected by the value of the steric factor
B
Experimentally determined value of frequency factor is higher than that predicted by arrhenius equation
C
Since $$P = 4.5,$$ the reaction will not proceed unless an effective catalyst is used
D
The value of frequency factor predicted by Arrhenius equation is higher than that determined experimentally
