Mns(s) + 2 h+ <===> mn2+ + h2s(g) at 25 °c the solubility product constant, ksp, for mns in 5 x 10¯15 and the acid dissociation constants k1 and k2 for h2s are 1 x 10¯7 and 1 x 10¯13, respectively. what is the equilibrium constant for the reaction represented by the equation above at 25 °c? (a) 1 x 10¯13 / 5 x 10¯15 (b) 5 x 10¯15 / 1 x 10¯7 (c) 1 x 10¯7 / 5 x 10¯20 (d) 5 x 10¯15 / 1 x 10¯20 (e) 1 x 10¯20 / 5 x 10¯15
