In an equilibrium reaction, Which of the following conditions indicates that maximum yield of the product will be obtained?
A. Equilibrium constant is very large B. ∆H – T∆S = O C. ∆ H > T ∆ S D. Equilibrium constant is less than zero Correct Answer: Option A – Equilibrium constant is very large
If the change in free energy of a system is -899 Jmol‾¹ and the entropy change is 10Jmol‾¹k‾¹ at 250C. Calculate the enthalpy change.
A. +2081 Jmol‾¹ B. -2081 Jmol‾¹ C. -649 Jmol‾¹ D. +649 Jmol‾¹ Correct Answer: Option A = +2081 Jmol‾¹ Explanation ∆G = ∆H – T∆S -899 = ∆H – 2980 ∆H = -899 + 2980 = + 2081...
How many faraday of electricity is required to produce 0.25 mole of copper?
A. 1.00F B. 0.01F C. 0.05F D. 0.50F Correct Answer: Option D = 0.50F Explanation Cu → Cu²+ + 2e 1 mole Cu requires 2f 0.25 mole Cu requires x x = 0.25×2/1 = 0.50fProducts
