🤓 Based on our data, we think this question is relevant for Professor Lekhi's class at UBC.
Given the following information,
HF(aq) ⇌ H+ (aq) + F - (aq) K c = 6.8 X 10-4
H2C2O4 (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)
E) 2.3 x 10-4
