The equilibrium constant is dependent on temperature. A change in temperature can shift the equilibrium towards products or reactants, resulting in a change in the equilibrium constant. In general, an increase in temperature favors the endothermic reaction, while a decrease in temperature favors the...
For any equilibrium reaction, what does {eq}K_\rm p {/eq} depend on? Expression of Equilibrium Constant: The equilibrium constant of a reaction is displayed in terms of a fraction.
