In which of the following cases, does the reaction farthest to completion?
Rate∝ Rate constant (k)
More the rate constant, more is the rate and less is time required.
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 × 1010 s−1. Calculate k at 318 K and Ea.
