**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:

$\overline{){\mathbf{\u2206}}{\mathbf{E}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{{\mathbf{E}}}_{{\mathbf{final}}}{\mathbf{}}{\mathbf{-}}{\mathbf{}}{{\mathbf{E}}}_{{\mathbf{initial}}}}$

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

###### Problem Details

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?
