Question

Write the expression for the equilibrium constant Kp for the following reaction. Enclose pressures in parentheses and do NOT write the chemical formula as a subscript. For example, enter (PNH3 )2 as (P NH3)2 . If either the numerator or denominator is 1, please enter 1 2 F2(g) + O2(g) ↔ 2 OF2(g)

Answer 1

Given , reaction ,

2F2 (g) + O​​​​​​2 (g) == 2 OF​​​​​2 (g)

As equilibrium constant for any reaction is given by the ratio of rate of forward reaction to the backward reaction . So,

K​​​​​​P = pressure of products / pressure of reactants

Here p in subscript means we are dealing equilibrium constant in terms of pressures .

So, Kp = (P OF2)2 / [ (P F2)2 (P O2) ]
