Question
Write the expression for the following reactions: H_2 (g) + CO_2 (g) doubleheadarrow CO (g) + H_2 O (g) K = [CO_2] (H_2 O)/[H_2] [CO_2] N_2 (g) + 3 H_2 (g) doubleheadarrow 2 NH_3 (g) [NH_3]^2/[N_2] [H_2]^3 HC_2 H_3 O_2 (aq) doubleheadarrow H^+ (aq) + C_2 H_3 O_2^- (aq) = [C_2 H_3 O_2 -] [H+]/[HC_2 H_3 O_2] HNO_2 (aq) doubleheadarrow H^+ (aq) + NO_2^- (aq) HC_2 H_3 O_2 (aq) + H_2 O (l) doubleheadarrow > H_3 O^+ (aq) + C_2 H_3 O_2^- (aq) HNO_2 (aq) + H_2 O (l) doubleheadarrow H_3 O^+ (aq) + NO_2^- (aq) 4 NH_3 (g) + 5 O_2 (g) doubleheadarrow 6 H_2 O (g) + 4 NO (g)Explanation / Answer
1)
a)
Kc = [CO][H2O] / [H2][CO2]
b)
Kc = [NH3]^2 / [N2][H2]^3
c)
Kc = [H+][C2H3O2-] / [HC2H3O2]
d)
Kc = [H+][NO2-] / [HNO2]
e)
liquid is not considered while writing Kc
Kc = [H3O+][C2H3O2-] / [HC2H3O2]
f)
Kc = [H3O+][NO2-] / [HNO2]
g)
Kc = [H2O]^6 [NO]^4 / [NH3]^4 [O2]^5
