How will an increase in temperature affect the following equilibrium? How will a decrease in the pressure of the reaction vessel affect it? 302 (g) 203 (g) AH = 285 kJ O An increase in temperature will shift the equilibrium to the left; a decrease in the pressure of the reaction vessel will shift the equilibrium to the right O An increase in temperature will shift the equilibrium to the right; a decrease in the pressure of the reaction vessel will shift the equilibrium to the right O An increase in temperature will shift the equilibrium to the right; a decrease in the pressure of the reaction vessel will shift the equilibrium to the left. O An increase in temperature will shift the equilibrium to the left; a decrease in the pressure of the reaction vessel will not affect the equilibrium

For the following equilibrium reaction; H2 + 12 2HI If you were to remove some H2, the reaction would shift If you were to remove some HI, the reaction would shift
