are you sure?
Apologies for the mistake in my previous response. The correct answer is:
c) An increase in temperature increases Keq in an endothermic system.
In an endothermic reaction, an increase in temperature will shift the equilibrium towards the reactants, since heat is considered a reactant in the reaction. Thus, increasing the temperature will decrease the value of Keq. Therefore, statement c is not true.
c) An increase in temperature increases Keq in an endothermic system.
In an endothermic reaction, an increase in temperature will shift the equilibrium towards the reactants, since heat is considered a reactant in the reaction. Thus, increasing the temperature will decrease the value of Keq. Therefore, statement c is not true.
