## Chemistry (4th Edition)

1. Identify if the reaction is exothermic or endothermic. $\Delta H \gt 0$: Endothermic $\Delta H \lt 0$: Exothermic (a) Endothermic. (b) Exothermic. (c) Neither. 2. If the reaction is endothermic raising the temperature favours the forward reaction, increasing products, increasing Kc; if it is exothermic, it will favor the reverse reaction, increasing reactants, decreasing Kc. (a) Increase the Kc (b) Decrease the Kc (c) Will not affect the Kc
