Vant Hoff Equation

[Daniel Kochanski 2L]

Can someone tell me the significance of the temperature dependence of equilibrium constants in chemical reactions? I'm confused the Van't Hoff equation helps in predicting the effect of temperature changes on reaction equilibrium and reaction rates?

Equilibrium constants are temperature dependent. The equilibrium constant of an exothermic reaction decreases as the temperature decreases. However, in an endothermic reaction, the equilibrium constant increases with increase in temperature. The Van't Hoff equation can be used to find the equilibrium constant when there is a change in temperature.

The temperature dependence of equilibrium constants helps predict how reactions respond to temperature changes. The Van't Hoff equation quantifies this relationship. Temperature changes can shift reactions towards products or reactants to maintain equilibrium, following Le Chatelier's principle. Additionally, higher temperatures generally lead to faster reaction rates due to increased kinetic energy. Understanding temperature's impact on equilibrium constants helps in controlling chemical processes.
