 For a gaseous reaction, the rate constant (k) is \mathrm{25 \times 10^{-3} \mathrm{Lmot}^{-1} \mathrm{5}^{-1} at 300 \mathrm{~K}}. If the rate constant increases by a factor of 3 as the temperature is raised to \mathrm{400 \mathrm{~K}.} What is the activation energy (Ea) for the reaction?

 

Option: 1

 2.5 \mathrm{~kJ} / \mathrm{mwl}


Option: 2

1.5 \mathrm{~kJ} / no ll


Option: 3

2.2 \mathrm{~kJ} / \mathrm{mer}


Option: 4

1.1 \mathrm{~kJ} / \mathrm{meol}
