WebSep 19, 2024 · Any reaction that reaches equilibrium is endothermic in one direction and exothermic in the other. This means that at equilibrium a change in heat content, with [change in equilibrium constant] or without [latent heat in a phase change] a change in temperature, will cause the reaction to establish a new equilibrium position. WebIf the temperature is increased, the equilibrium position moves in the direction of the endothermic process. For example, in the Haber process: N2(g) + 3H2(g) ⇌ 2NH3(g) (forward reaction is... WebOct 12, 2024 · In an exothermic reaction, heat seems to come from nowhere. However, no process can simply create energy, because doing so would violate the principle of conservation of energy.
