For the following reaction find K_p at 25°C and indicate whether K_p should increase or decrease as the temperature rises. NH₄HS(s)⇌ H₂S(g)+ NH₃(g)ΔH° = 83.47 kJ and ΔG° = 17.5 kJ at 25°C.

Given ΔG° = 17.5 kJ/mol, we can calculate the equilibrium constant (K) at 25°C (298 K) using the formula ΔG° = -RTlnK. Converting ΔG° to J/mol (17500 J/mol) and using R = 8.314 J/(mol·K), we find K ≈ 8.6 × 10^-4. Since the reaction is endothermic (ΔH° > 0), according to Le Chatelier's principle, increasing the temperature will shift the equilibrium to the right, thus increasing K.
