Hello everyone today. We have the following problem at the same temperature to reactions with equal activation energy have rates that differ by rate of That differ by a factor of five, explain So to explain this process, we have to use the rainy asse equation. So that's the Iranian equation and this equation is as follows. So we have the original equation here for the Iranians equation. And so we're going to equal that to the secondary reaction. So we have that difference by a factor of five. So we're gonna have a five and that's going to be multiplied by the activation energy of our second process. So in the question it stated that we had the same temperature and the same activation energy. So essentially the activation energy is going to become null. And so will the temperature and the gas constant since those will be null as well. And so since the activation energy and the temperature are the same, the frequency, the frequency factors differ By a factor of five. And so this is why because they have the same temperature and the same activation energy overall. I hope this helped. And until next time.
