Step 1: Understand that the van 't Hoff equation is a formula used in chemistry.
Step 2: Know that it helps us understand how the equilibrium constant (K) changes when the temperature changes.
Step 3: Remember that the equilibrium constant is a number that tells us the ratio of products to reactants at equilibrium in a chemical reaction.
Step 4: Realize that when temperature increases or decreases, the value of K can also change, and the van 't Hoff equation helps us calculate that change.
