### Question 4.30 in the organic chem book

Question 4.30 asks if a reaction can occur at room temperature if the known activation energy is 125 kJ/mol. Apparently, the answer is no, can someone explain why?

We use the Arrhenius equation and if we plug in 125 kj/mol into the equation, we end up with a very small value next to "A"
Arrhenius equation: k= A*(e^(-Ea/RT). Thus, when 125 is plugged in, it becomes k= A*(very small number), and thus, we can assume that k will be very small and since k is the rate constant, rate constant is very, very small at room temperature. Thus, reaction doesn't occur.

Yeah it could theoretically occur but it is just asking you to infer the most likely scenario
