In a first-order decomposition reaction. 36.8% of a compound decomposes in 7.6 min. how long (in min) does it take for 88.8% of the compound to decompose?

36.5 minutes

Explanation:

Expression for rate law for first order kinetics is given by:

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant  = 100

a - x = amount left after decay process  

a) for completion of 36.8 % of reaction  

b) for completion of 88.8 % of reaction  

It will take 36.5 minutes for 88.8% of the compound to decompose.

a is the answer to this question
