Give the equilibrium constant for the following equilibrium in terms of partial pressures:

$straight N subscript 2 left parenthesis straight g right parenthesis space plus space 3 straight H subscript 2 left parenthesis straight g right parenthesis space space space rightwards harpoon over leftwards harpoon space space space 2 NH subscript 3 left parenthesis straight g right parenthesis.$

Solution

Equilibrium constant in terms of partial pressures:
$straight K subscript straight p space equals space fraction numerator straight p subscript NH subscript 3 end subscript superscript 2 over denominator straight p subscript straight N subscript 2 end subscript space cross times space straight p cubed subscript straight H subscript 2 end subscript end fraction$
