A certain reaction has an enthalpy of Δ=44 kJ and an activation energy of a=61 kJ. What is the activation energy of the reverse reaction?

E = 17 kJ

Explanation:

The enthalpy of the reaction is:

Where:

Ep: is the energy of the products

Er: is the energy of the reactants

Similarly, the enthalpy of the reaction is related to the activation energy forward () and to the activation energy reverse () as follows:

Having that ΔH = 44 kJ and = 61 kJ, the activation energy of the reverse reaction is:

Therefore, the activation energy of the reverse reaction is 17 kJ.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
