Question

The decomposition of a substance x is a second order reaction. it takes 0.5 h for a solution that is initially 1.00 m to decrease to 0.50 m. how much time will it take for the concentration of a solution of x to decrease from 1.00 m to 0.25 m?

Answer 1

speed :

`((1.00 - 0.50))/(0.5) = 1 (m)/(h)`
the amount of time it take to decrease from 1.00 m to 0.25 m

`((1.00 - 0.25))/(1) = 0.75`
the answer is 0.75 h
