Step 1

The activation energy at 25˚C is 99.1 kJ/mol.

Let k1 is the rate constant at 25˚C and k2 at T2.

The conversion of temperature in Celsius to Kelvin is done by the formula.

Step 2

Therefore, the temperature (T1) is 289 K.

Similarly, the conversion of 99.1 kJ/mol into J/mol is as follows:

Step 3

It is given that rate constant (k2) is 10% greater than k1, which means k2 = 1.10 k1.

The form of Arrhenius e...
