Relationship between photon energy and kinetic energy of electrons. 🛠 Strategic MCQ Solving Tips

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

Physical Chemistry bridges physics and chemistry. To master MCQs, you must understand the behind chemical phenomena. 1. Chemical Thermodynamics This is the most frequent topic in competitive exams. First Law: Understand Relationship between photon energy and kinetic energy of

): 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. Physical Chemistry bridges physics and chemistry

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

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

. Watch for sign conventions (work done on vs by the system). This determines spontaneity. : Spontaneous. : Equilibrium. Entropy ( ΔScap delta cap S
