The following reaction is first order in each reactant: A+B-C rate = k[A][B] at 25.0C, k = 0.0850 M-'s-1 a. Initial concentrations both reactants = 0.100 M, find the half-life of the reaction at this temperature Half-life time Check b. For the same reaction and at the same temperature (in a.), find the time required for 75% of the reactants to react. Time required for 75% of the reactants to react = s Check c. For the reaction at the same temperature (in a.) but the initial concentration [A] = 0.200 M and [B] 0.100 M, find the time required for 75% of B to react. Time required for 75% of B to react = Check
