($A$) a high activation energy usually implies a fast reaction.
($B$) rate constant increases with increase in temperature. This is due to a greater number of collisions whose energy exceeds the activation energy.
($C$) higher the magnitude of activation energy, stronger is the temperature dependence of the rate constant.
($D$) the pre-exponential factor is a measure of the rate at which collisions occur, irrespective of their energy.
$CO(g) + Cl_2(g) \rightleftharpoons COCl_2(g)$
The reaction carried out in a $500\,mL$ flask. At equilibrium, $0.3\,mol$ of phosgene, $0.1\, mol$ of $CO,$ and $0.1\,mol$ of $Cl_2$ are present. The equilibrium constant of the reaction is
