. Watch for sign conventions (work done on vs by the system). This determines spontaneity. : Spontaneous. : Equilibrium. Entropy ( ΔScap delta cap S
): Look for phase changes. Gas formation always increases entropy. 2. Chemical Kinetics Focus on the and order of reactions . Zero Order: Rate is independent of concentration. First Order: Half-life ( t1/2t sub 1 / 2 end-sub ) is constant and independent of initial concentration. MCQ Physical Chemistry
Relate current and time to the mass of substance deposited. : Spontaneous
This is the #1 reason students miss marks. Always convert units to SI (Joules, Kelvin, Liters, Atm) before plugging them into formulas. Gas formation always increases entropy
If the concentration of a reactant is doubled and the rate of reaction quadruples, what is the order of the reaction? A) Zero Order B) First Order C) Second Order D) Third Order Logic: Use the formula: Answer: C (Second Order) 📚 Study Resources
