Assume That the Following $\underline{\text{ endothermic }}$ Chemical Reaction Is at Equilibrium

Multiple Choice

Assume that the following $\underline{\text{ endothermic }}$ chemical reaction is at equilibrium.
C(s) + H₂O(g) H₂(g) + CO(g)
Which of the following statements is/are CORRECT?
1) Increasing the concentration of H₂(g) will cause the reaction to proceed in the backward direction,increasing the equilibrium concentration of H₂O(g) .
2) Decreasing the temperature will cause the reaction to proceed in the forward direction,increasing the equilibrium concentration of CO(g) .
3) Increasing the amount of C(s) will cause the reaction to proceed in the forward direction,increasing the equilibrium concentration of CO(g) .

A) 1 only
B) 2 only
C) 3 only
D) 1 and 2
E) 1,2,and 3
