Question

75% of a first order reaction was found to complete in 32 min. when will 50% of the same reaction complete

Answer 1

Answer:

Explanation:

For a first-order reaction, we have:

t 75% =2t 50%

​

Given: t 75%=32 min

Substituting the values in the above expression, we get-

32 min =2 t 50%

​

t 50% =16 mins

Hence, 50% of the reaction would have been completed in 16 mins.
