Question

For each of the scenarios, identify the order with respect to the reactant, A. A⟶products

A three‑fold increase in the initial concentration of A leads to a 1.73‑fold increase in the initial rate.

Order?

The time required for [A] to decrease from [A]0 to [A]0/2 is equal to the time required for [A] to decrease from [A]0/2 to [A]0/4. ([A]0 means naught)

Order?

The rate of decrease of [A] is a constant.

Order?

Answer 1

A ==> Products

Rate = k[A]^x this is the rate equation for this reaction.

Three fold increase in concentration -> 1.73 fold increase in rate: [3]^x = 1.73 and x = 1/2 order

Half life is independent of concentration = 1st order

Rate of decrease is constant = 1st order
