Calculate the free energy change at 298 K for the reaction; Br 2 ( λ ) + Cl 2 (g) ⎯→ 2BrCl(g). For the reaction Δ Hº = 29.3 kJ & the entropies of Br 2 ( λ ),Cl 2 (g) & BrCl(g) at the 298K are 152.3,223.0,239.7 J mol –1 K –1 respectively
Text Solution
Verified by ExpertsThe correct answer is:
A
Δ G = 29.3 × 10 3 – (2 × 239.7 – 152.3 – 223) × 298 = – 1721.8 Joule.
