Find out the value of equilibrium constant for the following reaction at 298K, `2NH_3(g) + CO_2(g) iff NH_2 CONH_2 (aq) + H_2O (l)` Standard Gibbs energy change, `DeltaG^@` , at the given temperature is `-13.6 kJ "mol"^(-1)`

Text Solution

Verified by Experts

Given : `T = 298 K `
` Delta G_r^@ = -13.6kJ "mol"^(-1)`
` =- 13600 J "mol"^(-1)`
` Delta G^@ = - 2.303 RT log K_(eq)`
` log K_(eq) = (-Delta G^@)/(2.303 RT)`
`log K_(eq) = (13.6 kJ "mol"^(-1) )/(2.303 xx 8.314 ) xx 10^(-3) JK^(-1) "mol"^(-1) xx 298 K`
` log K_(eq) = 2.38`
` K_(eq) = "antilog " (2.38)`
`K_(eq) = 239.88 `
