Question 55
MTNAT2 marksNeeds review
Consider the following cell reaction:
Mg + Cd
⇌ Mg
+ CdThe standard Gibbs free energy change for the reaction is _____ kJ (rounded off to an integer).
Given: Standard oxidation potentials for the reactions with respect to standard hydrogen electrode are:
Mg ⇌ Mg
+ 2e
E° = 2.37 VCd ⇌ Cd
+ 2e
E° = 0.403 VFaraday’s constant = 96500 C mol
