The rate constant for a first order reaction is 3.5-10-3 S-1 at 25°C. The rate constant
at 77°C is 0.70 S-1. What is the activation
energy for the reaction?
[ ? ]kJ/mol
Recall that R = 8.314 J/mol K
-hurry it’s a test

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
