Question

Molecule A decomposes to give B and C. The following figures represent two experiments conducted to study this decomposition reaction. Flask 2 is found to react four times faster than Flask 1. What is the rate law for the decomposition of A? In case of first order type "1". Explain your reasoning in terms of molecular collisions. At the molecular level, the rate-determining step could be a reaction between A molecules. For this process, the rate increases because the concentration results in a rate of collisions.

Explanation / Answer

Rate = k [A]^2

two

we find order is 2

Rate is increased 4 times when [A] is 2 times

it implies order is 2
