What is the value of the equilibrium constant at this temperature? Number Tools × 102 Hint Previous Give Up & View Solution e Check Answer 0 Next Ext

Explanation / Answer

A:- Balanced elementary reaction,

2 H2O(g)    <========>   2 H2(g)    +    O2(g)

Equilibrium constant, Kp = ((P2H2 * PO2) / (P2H2O))

                                       = ((0.00900)2 * (0.00500)) / (0.0350)2

                                     Kp = 3.306 * 10^-4
