When ethyl chlоride, CH3CH2Cl, is dissоlved in 1.0 M NаOH, it is cоnverted into ethаnol, CH3CH2OH, by the reаction CH3CH2Cl + OH– → CH3CH2OH + Cl–At 25°C the reaction is first order in CH3CH2Cl, and the rate constant is 1.0 × 10–3 s–1. If the activation parameters are A = 3.4 × 1014 s–1 and Ea = 100.0 kJ/mol, what will the rate constant be at 40.°C?
