The equilibrium constant for a reaction is 10. What will be the value of ∆Gθ? R = 8.314 JK– 1 mol–1 , T = 300 K.
From the expression, ∆Gθ = –2.303 RT logKeq ∆Gθ for the reaction, = (2.303) (8.314 JK–1 mol–1 ) (300 K) log10 = –5744.14 Jmol–1 = –5.744 kJ mol–1

Justify the statements: a) Reactions with ΔG0 < 0 always have an equilibrium constant greater than 1.
(a) –ΔG0 = RTlnK. Thus, if ΔG0 is less than zero, i.e., it is –ve and hence K will be greater than 1. (b) Under ordinary conditions, the average energy of...

For the equilibrium, 2NOCl(g) ⇌ 2NO(g) + Cl2(g) the value of the equilibrium constant, Kc is 3.75×10–6 at 1069 K
We know that, Kp = Kc (RT)Δn For the above reaction, Δn = (2+1) – 2 = 1 Using, Kp = Kc (RT)Δn Kp = 3.75 ×10–6 (0.0831 × 1069) Kp = 0.033.

Glucose or sucrose are soluble in water but cyclohexane or benzene (simple six
A glucose molecule contains five −OH groups while a sucrose molecule contains eight −OH groups. Thus, glucose and sucrose undergo extensive H-bonding with water. Hence, these are soluble in water. But...
