The following reactions start at equilibrium. A stress is added and the position of equilibrium shifts. After the indicated stress is added which of the following reactions will proceed towards products? The added stress is the part listed inside the braces {} YOU MUST CHOOSE ALL OF THE CORRECT RESPONSES. Don't just pick one correct answer unless there is indeed only one correct answer.
A). NH₃(g) + HCl(g) NH₄Cl(s) {and the volume is doubled}
B). Cl(s) + 2H₂(g) CH₄ {and a catalyst is added}
C). CO₂(g) + H₂(g) H₂O (g) + CO (g) {and volume is reduced}
D). N₂(g) + 3H₂(g) 2NH₃(g) {and the volume is reduced}
