Determine the rate law for the overall reaction (where the overall rate constant is represented as? consider the following mechanism
step 1: 2a > b+c slow
step 2: b+c > e fast

overall: 2a > e
determine the rate law for the overall reaction (where the overall rate constant is represented as k
rate=
explain how you got the answer and show steps
