Remind students that the value of K p will increase with increase in temperature, whereas it will not be affected by changes in pressure despite a shift in the position of equilibrium.

WebAnswer = make it smaller. To see this, write the K eq expression for the reation: K eq = [HCl] 2 / ([H 2] [Cl 2]) As the equilibrium shifts to the left, the [HCl] goes down and both the [H 2] and [Cl 2] increase. This makes the numerator smaller and the denominator larger. The K eq decreases in value and heat is added to an exothermic reaction. WebThe temperature plays an important role in determining the Gibbs free energy and spontaneity of a reaction. Δ G = Δ H – T Δ S. If we examine the Gibbs free energy change equation, we can cluster the components to create two general terms, an enthalpy term, Δ H, and an entropy term, – T Δ S. Depending on the sign and magnitude of each ...
