Step 1

Given information:

Activation energy = 45.0 kJ/mol

Rate constant (k1) = 1.8×104 M-1s-1

Temperature (T1) = 222.0 °C

Temperature (T2) = 266.0 °C

Step 2

Arrhenius equation is represented as follows:

Step 3

Since the temperature is given in degree Celsius so it would be converted into Kelvin first as follows:
