Multiple Choice

Assume that the following chemical reaction is at equilibrium.
2 ICl(g) I₂(g) + Cl₂(g) $~~~~~~~~$ $~~~~~~~~$ $\Delta$ H ^$\circ$ = +26.9 kJ

At 25 ^$\circ$ C,K_p = 2.0 $\times$ 10⁵.If the temperature is increase to 45 ^$\circ$ C,which statement applies?

• A) K_p will decrease and the reaction will proceed in the backward direction.
• B) K_p will decrease and the reaction will proceed in the forward direction.
• C) K_p will remain unchanged and the reaction will proceed in the forward direction.
• D) K_p will increase and the reaction will proceed in the backward direction.
• E) K_p will increase and the reaction will proceed in the forward direction.
