Solution:
Given that for a first-order reaction:
t(60%) = 50 min
We need to find t(93.5%)
We know that the time required for a reaction to reach a certain percentage completion is inversely proportional to the rate constant of the reaction.
Therefore, we can use the following relation:
t(60%)/t(93.5%) = (ln 2)/(ln 1 - 0.6) = 1.609
Solving for t(93.5%):
t(93.5%) = t(60%)/1.609 = 31.09 × 1.609 = 50 min
Therefore, the correct option is c) 50 min.
Explanation:
The question is based on the concept of first-order reactions and the relation between the time required for a certain percentage completion of the reaction and the rate constant of the reaction. The solution involves the use of the relation between the time required for 60% and 93.5% completion of the reaction and the rate constant of the reaction. The answer is obtained by applying the relation and solving for the required time.
