[Select all that apply] Group of answer choices N2O4 (g) ⇄ 2 NO2 (g) N2 (g) + 3 H2 (g) ⇄ 2 NH3 (g) CaCO3 (s) ⇄ CaO (s) + CO2 (g) H2 (g) + I2 (g) ⇄ 2 HI (g) Co (s) + 2H+ (aq) ⇄ Co2+ (aq) + H2 (g)arrow_forwardSuppose you are given the reaction A(g) + B(g) C(g) + D(g). You have the gases A, B, C, and D at equilibrium. Upon adding gas B, the value of K: Select one: a. increases, because by adding A more products are made, increasing the product to reactant ratio b. does not change, as long as the temperature is constant c. depends on whether the reaction is endothermic or exothermic d. does not change, because A does not figure into the product to reactant ratio e. decreases, because A is a reactant so the product to reactant ratio decreasesarrow_forwardHow is the reaction quotient different from an equilibrium constant for a given reaction?
