If K1 &K2be first and second ionisation constant of H3PO4 and K1>>K2 which is incorrect
The equilibrium constants for the reactions are:
H3PO4K1⇌H++H2PO−4;K1H2PO−4K2⇌H++HPO2−4;K2HPO2−4K3⇌H++PO3−4;K3
The equilibrium constant for, H3PO4⇌3H++PO3−4 will be:
For Cu2+ ion in [Cu(H2O)4(en)]2+, [Cu(H2O)2(en)2]2+ and [Cu(en)3]2+ with the stability constant k1, k2 and k3 respectively, which of the following holds true?
Equilibrium constants K1 and K2 for the following equilibria are
NO(g) + 0.5O2(g) →K1 NO2(g) and 2NO2(g) →K2 2NO(g) + O2(g)
