Consider the reaction: J2(g) + R2(g) ⇄ 2JR(g). Let a square represent an atom of J and a circle represent an atom of R. The value for the equilibrium constant for this reaction at 25°C is greater than 1. The drawing below labeled Before shows a small representative volume of a container held at 25°C immediately after J2 and R2 have been added but before reaction between J2 and R2 to give JR has occurred. Circle the letter of each...
