QUESTION 4 In general, as the temperature increases, the equilibrium constant, Kea -1 Increases only for an endothermic reaction Increases regardless of whether it is an endothermic or exothermic reaction Increases only for an exothermic reaction Is constant regardless of whether it is an endothermic or exothermic reaction Is constant only for nonspontancous reactions QUESTION 5 The equation of the line for the graph obtained for a thermodynamic experiment is y= (13111 K)x-29.655. Use this to answer the next two questions Determine the value of the standard enthalpy change, ΔH. 109 kJ/mol -247 kJ/mol -1577 kJ/mol 1577 kJ/mol -109 kJ/mol

Answer #1

1. When the forward reaction is exothermic , increasing the temperature decreases the value of equilibrium constant.

And, when the forward reaction is endothermic, increasing the temperature increases the value of the equilibrium constant.

So, it increases only for endothermic reaction.

Option A.
