Quizplus · Accepted Answer

According to Le Chatelier's principle, when the temperature is increased, the equilibrium will shift in the direction that absorbs heat (or endothermic direction in this case). Since the forward reaction is endothermic (198 kJ/mol), increasing the temperature will shift the equilibrium to the right to consume the excess heat. As a result, the concentration of products (2SOS1U1B12S1U1B0 and OS1U1B12S1U1B0) will increase, while the concentration of reactants (2SOS1U1B13S1U1B0 and OS1U1B1) will decrease. This will result in an increase in the value of the equilibrium constant, K.
