75% of a zero order reaction completes in 4h, 87.5% of the same reaction completes in:

A

6 h

B

12 h

C

8 h

D

2 h

Correct Answer

Option A

Detailed Explanation

For a zero order reaction, the time taken for completion is proportional to the concentration. Using the relation, t₇₅% = 3/2 × t₂₅%, we find t₈₇.₅% = 3/2 × 4 = 6h.
