Rate constant "answer check" 1. The problem statement, all variables and given/known data given that activation energy for a certain reaction is 48 kJ/mol, and the rate constanct is 2.5 x 10-2 s-2 at 15 degrees Celsius. waht is the rate constant at 37 degrees Celsius? 2. Relevant equations ln k1/k2 = [Ea/R] [(T1-T20)/(T1*T2)] 3. The attempt at a solution my answer is k1= .1037740579 = .104 s-1 thank you for all the help!!
