For the chemical reaction X Y, the standard reaction Gibbs energy depends on temperature T (in K) as Δ r G° (in kJ mol –1 ) = 120 – 8 3 T. The major component of the reaction mixture at T is :

1. Y if T = 300 K
2. Y if T = 280 K
3. X if T = 350 K
4. X if T = 315 K CAREER POINT CAREER POINT , CP Tower, IPIA, Road No.1, Kota (Raj.), : 0744-6630500 | www.ecareerpoint.com Email: info@cpil.in Page # 8 JEE Main Online
