Question

Nickel metal can be prepared by the reduction of nickel oxide: NiO(s)+ CO(g)⇌ CO₂(g)+ Ni(s) At 936 K,K_p = 4.54 × 10³ and at 1125 K,K_p = 1.58 × 10³.Which statement is true?

Quizplus · Accepted Answer

The decrease in Kp with increasing temperature indicates that the reaction is exothermic, as exothermic reactions have lower equilibrium constants at higher temperatures.
