The standard Gibbs energy change at 300 K for the reaction is
2A[IMAGE] B + C is 2494.2 J. At a given time, the
composition of the reaction mixture is = 2
and = 8.314
Show answer and solution
DG = DGº + RT ln Q
= 2494.2 + 8.314 × 300 ln 4
= positive èkukREkd
Since, ΔG is positive so, Q > K, so reaction shifts in reverse
direction.

= 2494.2 + 8.314 × 300 ln 4
= positive èkukREkd
Since, ΔG is positive so, Q > K, so reaction shifts in reverse
