Answer

(a) Less products. (b) More products. (c) More products. (d) Less products.

Work Step by Step

Increasing the temperature favors the endothermic reactions (with positive $\Delta H^o_{rxn}$), and decreasing it favors the exothermic reactions (negative $\Delta H^o_{rxn}$). Therefore: if the forward reaction is endothermic, increasing the temperature favors products, if it is exothermic, increasing the temperature favors reactants. (a) Negative: Exothermic: Favors Reactants: Less products. (b) Positive: Endothermic: Favors Products: More products. (c) Endothermic: More products. (d) Exothermic: Less products.
