Problem: A system goes from state 1 to state 2 and back to state 1.Is E the same in magnitude for both the forward and reverse processes?

FREE Expert Solution

We’re being asked to determine if the change in energy E is the same in magnitude for both the forward and reverse process


State 1 ⇌ State 2 


Recall that for the change in energy, ΔE, of a reaction is given by:

E = Efinal - Einitial


Let's illustrate the change in energy for both processes then compare themWe will do the following steps:

Step 1: Derive the equation for the change in energy of the forward reaction

Step 2: Derive the equation for the change in energy of the reverse reaction

Step 3: Compare the forward and reverse reaction change in energy
