Correct answer is (a) X if T = 315 K

Q. For the chemical reaction $X ⇌ Y$ , the standard reaction Gibbs energy depends on temperature $T$ (in $K$ ) as:
$Δ r G^{\circ} ($ in $K J m o l^{- 1}) = 120 - \frac{3}{8} T$
The major component of the reaction mixture at $T$ is:

$X$ if $T = 315 K$

$X$ if $T = 350 K$

$Y$ if $T = 300 K$

$Y$ if $T = 280 K$

Correct answer is (a) $X$ if $T = 315 K$

Q. For the chemical reaction X⇌Y, the standard reaction Gibbs energy depends on temperature T (in K ) as: ΔrG∘( in KJmol−1)=120−83​T The major component of the reaction mixture at T is:

X if T=315K

X if T=350K

Y if T=300K

Y if T=280K
