Chemistry KS3/GCSE: Endothermic and exothermic reactions
WebIn the Haber process, the forwards reaction is exothermic, so the reverse reaction is endothermic. N2(g) + 3H2(g) ⇌ 2NH3(g) (forwards reaction is exothermic) This means that as the... WebN 2 (g) + 3H 2 (g) ⇌ 2NH 3 (g) (forward reaction is exothermic) If the forward reaction is exothermic, the backward reaction must be endothermic. Therefore, if the temperature is increased, the equilibrium position moves in the endothermic direction (to the left) to reduce the temperature. This means that less ammonia (NH 3) will be produced ... Webendothermic reactions, and are useful when cooking and baking cakes.
