The order of the reaction, ? → products, is being determined through the half-life method. Two setups at the same temperatures but different starting concentrations of A were investigated. For the first run, the initial concentration of A was 0.78 M and the halflife was determined to be 45 minutes. In the second run, the initial concentration of A was 1.32 M. Determine the following : a. If the reaction is 1st order, what should be the half-life of the second run in minutes?

Question
Half-life of a reaction
The order of the reaction, ? → products, is being determined through the half-life method. Two setups at the same temperatures but different starting concentrations of A were investigated. For the first run, the initial concentration of A was 0.78 M and the halflife was determined to be 45 minutes. In the second run, the initial concentration of A was 1.32 M.
Determine the following :
a. If the reaction is 1st order, what should be the half-life of the second run in minutes?
b. If the reaction is 2nd order, what should be the half-life of the second run in minutes?
c. If the reaction is 0th order, determine the concentration of A in the second run after 152.3 minutes.
