Sample Question 1
Thermodynamics & Electrochemistry EASY • Chemistry (Secondary & College Level)
What is the criterion for a chemical process to be spontaneous at constant temperature and pressure?
A Change in Gibbs Free Energy Delta G < 0 (negative)
B Delta G > 0
C Delta H > 0 exclusively
D Delta S_system < 0
✓ Correct Answer: A - Change in Gibbs Free Energy Delta G < 0 (negative)
📖 Step-by-Step Solution & Conceptual Rationale:
A reaction is thermodynamically spontaneous when Delta G = Delta H - T*Delta S is negative.
Sample Question 2
Thermodynamics & Electrochemistry EASY • Chemistry (Secondary & College Level)
In an electrochemical galvanic (voltaic) cell, which processes occur at the Anode and Cathode respectively?
A Anode: Oxidation (loss of electrons); Cathode: Reduction (gain of electrons)
B Anode: Reduction; Cathode: Oxidation
C Both electrodes undergo oxidation
D No electron transfer takes place
✓ Correct Answer: A - Anode: Oxidation (loss of electrons); Cathode: Reduction (gain of electrons)
📖 Step-by-Step Solution & Conceptual Rationale:
Remember 'An Ox and Red Cat': Anode is always the site of Oxidation; Cathode is always the site of Reduction.
Sample Question 3
Thermodynamics & Electrochemistry MEDIUM • Chemistry (Secondary & College Level)
What is Faraday's First Law of Electrolysis?
A The mass m of substance deposited or liberated at an electrode is directly proportional to the quantity of electric charge Q passed (m = Z * I * t)
B m is inversely proportional to current
C Electrode mass is independent of time
D Voltage is proportional to resistance
✓ Correct Answer: A - The mass m of substance deposited or liberated at an electrode is directly proportional to the quantity of electric charge Q passed (m = Z * I * t)
📖 Step-by-Step Solution & Conceptual Rationale:
Faraday's first law states m = Z * Q = Z * I * t, where Z is the electrochemical equivalent.
Sample Question 4
Thermodynamics & Electrochemistry MEDIUM • Chemistry (Secondary & College Level)
The bond order of nitrogen molecule (N2) according to Molecular Orbital Theory is:
A 3
B 2
C 1
D 2.5
✓ Correct Answer: A - 3
📖 Step-by-Step Solution & Conceptual Rationale:
N2 has 10 valence electrons: Bond Order = (Nb - Na)/2 = (8 - 2)/2 = 3 (representing a stable triple bond).
