(choose chapter or problem)

Which of the following reactions lies to the right, favoring the formation of products, and which lies to the left, favoring formation of reactants?

(a) \( \mathrm{NO}(g)+\mathrm{O}_{2}(g) \rightleftharpoons 2 \mathrm{NO}_{2}(g) \quad K_{p}=5.0 \times 10^{12}\)

(b) \(2 \mathrm{HBr}(g) \rightleftharpoons \mathrm{H}_{2}(g)+\mathrm{Br}_{2}(g) \quad K_{c}=5.8 \times 10^{-18}\)

Text Transcription:

2 NO1g2 + O2(g) \rightleftharpoons 2 NO2(g) Kp = 5.0 X 1012

2 HBr(g) \rightleftharpoons H2(g) + Br21g2 Kc = 5.8 X 10-18
