To solve this problem, we need to use the Arrhenius equation and the concept of temperature dependence of reaction rates.The Arrhenius equation is given by:where is the rate constant, is the pre-exponential factor, is the activation energy, is the universal gas constant, and is the temperature in Kelvin.The ratio of rate constants at two different temperatures can be expressed as:Given that the rate quadruples, we have:Let's convert the temperatures from Celsius to Kelvin:KKSubstitute the values into the equation:Take the natural logarithm on both sides:Given convert to natural log:Substitute back:Calculate the difference in reciprocals:Substitute this into the equation:Solve for J/molConvert to kJ/mol:kJ/molTherefore, the activation energy is approximately kJ/mol.This corresponds to Option 3.
