The rate at which a certain Australian tree cricket chirps is 194/min at 28°C, but only 47.6/min at 5°C, From these data calculate the energy of activation for the chirping process. (Hint: the ratio of the rates is equal to the ratio of the rate constants.) Enter in units of kJ/mol.

The energy of activation for the chirping process is 283.911 kJ/mol

Explanation:

According to the Arrhenius equation,

The expression used with catalyst and without catalyst is,

where,

= rate of reaction at = 194/min

= rate of reaction at   = 47.6 /min

= activation energy

R = gas constant = 8.314 J/Kmol

tex]T_1[/tex] = initial temperature =

tex]T_1[/tex] = final temperature =

Now put all the given values in this formula, we get

Thus the energy of activation for the chirping process is 283.911 kJ/mol

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
