This is the #1 reason students miss marks. Always convert units to SI (Joules, Kelvin, Liters, Atm) before plugging them into formulas.

Understand how temperature affects the rate constant ( 3. Electrochemistry This section is heavily numerical. MCQ Physical Chemistry

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 This is the #1 reason students miss marks

In thermodynamics, if a process is exothermic and entropy increases, it must be spontaneous. Eliminate any options suggesting otherwise. Electrochemistry This section is heavily numerical

): 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.
