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.
