Question

In a closed system A(s) gives 2B(g) +3C (g) if the partial pressure of c is doubled then the partial pressure of b will be

Answer 1

For the reaction, the equilibrium constant is given by K = [P_C]³x[P_B]² as A is a solid, its pressure is not counted so when thepressure of C is doubled, the new K' = 8x[P_C]³x[P'_B]² this has to be neutralized by decreasingP_B so that the value of K becomes the previous value. equating both equations [P_C]³x[P_B]²= 8x[P_C]³x[P'_B]² hence[P'_B]²=[P_B]²/8 hence[P'_B] =[P_B]/2√2
