From the following equilibrium constants, calculate the equilibrium constant for the reaction HO2CCO2H ----->2H+ + C2O-24
k1=5.6x10-2
k2=5.4x10-5
HO2CCO2H (aq) ---------------> H^+ (aq) + HO2CCO2^- (aq) K1 = 5.6*10^-2
K1 = [H^+][HO2CCO2^-]/[HO2CCO2H]
HO2CCO2^- (aq) -------------> H^+ (aq) + C2O4^2- (aq) K2 = 5.4*10^-5
K2 = [H^+][C2O4^2-]/[HO2CCO2^-]
HO2CCO2H(aq) ----->2H+(aq) + C2O4^2-(aq)
K = [H^+]^2[C2O4^2-]/[HO2CCO2H]
K1*K2 = [H^+][HO2CCO2^-]/[HO2CCO2H] * [H^+][C2O4^2-]/[HO2CCO2^-]
K1*K2 = [H^+]^2[C2O4^2-]/[HO2CCO2H]
K1*K2 = K
K = K1*K2
= 5.6*10^-2 * 5.4*10^-5
= 3.024*10^-6
HO2CCO2H ----->2H+ + C2O-24 K = 3.024*10^-6 >>>>answer
