The value of the solubility product constant for ag2co3 is 8.5 × 10‒12 and that of ag2cro4 is 1.1 × 10‒12. from this data, what is the value of kc for the reaction, ag2co3(s) + cro42‒(aq) → ag2cro4(s) + co32‒(aq) a) 9.6 × 10‒12 b) 7.7 c) 1.1 × 1023 d) 1.3 × 10‒1 e) 9.4 × 10‒24

Value of for the given reaction is 7.7

Explanation:

Where represents solubility product

For the given reaction, (concentration of pure solids remain constant during reaction. Hence their concentration is taken as 1 to exclude them from equilibrium constant expression)

So,

or,

Hence option (B) is correct
