Solution: Given the following information,HF(aq) ⇌ H+ (aq) + F - (aq)                      K  c = 6.8 X 10-4H2C2O4 (aq) ⇌ 2H+ (aq) + C 2O4-2 (aq)      K c = 3.8 X 10-6determine the value of Kc for the reaction2

Problem

Given the following information,

HF(aq) ⇌ H+ (aq) + F - (aq)                      K  c = 6.8 X 10-4

H2C2O(aq) ⇌ 2H+ (aq) + C 2O4-2 (aq)      K c = 3.8 X 10-6

determine the value of Kc for the reaction

2HF(aq) + C2O4-2 (aq) ⇌ 2F - (aq) + H2C2O4 (aq)
