Step by step solution would be greatly appreciated.

How many of the following statements are true regarding the chemical reaction below? 2 IBr (g) I_2 (g) + Br_2 (g) K_P = 8.5 times 10^-3; delta H > 0 Decreasing the temperature of the reaction vessel will increase the concentration of the products. If pressure is increased at constant temperature, the concentration of reactants will decrease. Reactants dominate at equilibrium. Adding IBr (g) will increase the partial pressures of I_2 and Br_2. Adding a catalyst will increase K_p. 1 2 3 4 5

Explanation / Answer

I ) delta H > 0 means it is endothermic reaction . endothermic reaction favours at higher temperatures . high temperature needs for forward direction and low temperature needs for backward direction.

so this one is False

II) False

pressure has no effect on this equilibrium because product moles = reactant moles = delta n = 0

III) True

Kp < 1 so reactants dominent

if Kp > 1 products dominent

IV ) True

because any one of the reactant added to equilibrium the reaction shifts to forward direction

V) False

catalyst has no effect on Kp . only temperature will effect Kp

so answer : B ) 2

only two statements are correct
