For a certain reaction, the activation energy is 52.1 kJ/mole. By what ratio will the rate constant change if the temperature is decreased from 175C to 75C?

Use the Arrhenius equation and remember to insert Ea in J/mol and not kJ/mol.

That answer is too basic... Could someone show the steps on how to solve this one? I keep on getting the 55.67 as an answer but the correct one is 0.0179.

@Eunji flip your numbers when finding for ratio
