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:
Let's illustrate the change in energy for both processes then compare them. We 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
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?
