Solution

The correct option is B $K = 10^{2}$
Rate of reaction is decided by the rate constant of the reaction. The higher rate constant implies a faster rate of the reaction.

Also, the extent of completion of reaction depends on its equilibrium constant, K. If K is greater, the extent of completion is greater.

Hence, the correct option is $A$

The time required for 10% completion of a first order reaction at 298 K is

equal to that required for its 25% completion at 308 K. If the value of A is

4 × 10¹⁰s⁻¹. Calculate k at 318 K and E_a.

K_{1} = 10^{6}, K_{2} = 10^{- 4}, K_{3} = 10, K_{4} = 1
