JEE Main 2016 · 10 Apr · Shift 1, Chemistry question 37

A solid XY kept in an evacuated sealed container undergoes decomposition to form a mixture of gases X and Y at temperature T. The equilibrium pressure is 10 bar in this vessel. KpK_p for this reaction is :

Choose one option
Answer and worked solution

Official answer: C

XY(s)⇌X(g)+Y(g)\ce{XY(s) <=> X(g) + Y(g)} gives equal partial pressures of 5 bar each, so Kp=5×5=25K_p=5\times5=25.
