The standard Gibbs energy change at `300K` for the reaction `2AhArrB+C` is 2494. `2J`. At a given time, the composition of the reaction mixture is `[A]=1/2, [B]=2` and `[C]=1/2`. The reaction proceeds in the
`(R=8.314JK//"mol"e=2.718)`

Options

A. forward direction because `Q lt K_(c)`
B. reverse direction because `Q lt K_(c)`
C. forward direction because `Q gt K_(c)`
D. reverse direction because `Q gt K_(c)`

Answer

D

Explanation

the reaction proceeds in the reverse direction as
`Q gt K_(c).` For detalis consult example 7.14.
