Write the expression for the acid-dissociation constant Ka for HC4H7O2. (Concentration equilibrium expressions take the general form: Kc = [C]c / [A]a . [B]b. Subscripts and superscripts that include letters must be enclosed in braces {}.)
At 127°C, the equilibrium constant for
N2O4(g) ⇌ 2 NO2(g) is K = 47.9. What is the value of Kc at that temperature ?
