113.2.1 Influence of temperature
The influence of temperature can be obtained by differentiation of the equation above to
lead:
−lnKeq=∆RTHR−∆RSR
as known as thevan’t Hoff^2 equation. Therefore, for exothermic reaction (∆Hr< 0 ) an
increase in temperature will decrease the ∆HR/RT quantity, leading to a lower Keq,
conversely for an endothermic reaction.
