The rate constant of the elementary reaction BH, (aq) + NH (aq) → BH;NH3 (aq) + H2 (g) is k = 1.94 x 10-4L mol¯' s-' at 30.0°C, and the reaction has an activation energy of 161 kJ mol. (a) Compute the rate constant of the reaction at a tem- perature of 40.0°C. (b) After equal concentrations of BH (aq) and NH, (aq) are mixed at 30.0°C, 1.00 × 10ª s is required for half of them to be consumed. How long will it take to consume half of the reactants if an identical experi- ment is performed at 40.0°C?
