For the following equilibrium, K_c = 6·3 × 10¹⁴at 1000 K
$space NO left parenthesis straight g right parenthesis space plus space straight O subscript 3 left parenthesis straight g right parenthesis space rightwards harpoon over leftwards harpoon space space NO subscript 2 left parenthesis straight g right parenthesis plus straight O subscript 2 left parenthesis straight g right parenthesis$
both the forward and reverse reactions in the equilibrium are elementary bimolecular reactions. What is K_c for the reverse reaction?

Solution

For the equilibrium.
$space NO left parenthesis straight g right parenthesis plus space straight O subscript 3 left parenthesis straight g right parenthesis rightwards harpoon over leftwards harpoon space NO subscript 2 left parenthesis straight g right parenthesis space plus space straight O subscript 2 left parenthesis straight g right parenthesis space space space space space straight K subscript straight C space equals space 6.3 space cross times space 10 to the power of 14$
$space therefore space space For space the space reverse space reaction space straight K subscript straight c space equals space 1 over straight K subscript straight c space equals space fraction numerator 1 over denominator 6.3 space cross times space 10 to the power of 14 end fraction space equals space 1.59 space cross times space 10 to the power of negative 15 end exponent$
