NCERT Class 12 Chemistry Chapter 3 Chemical Kinetics Test Mock Test
This free online test covers Chapter 3, Chemical Kinetics, from the NCERT Class 12 Chemistry-I textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.Of the three things chemists want to know about a reaction, the one that chemical kinetics answers is:
- AThe feasibility of the reaction, predicted from the sign of the Gibbs energy change
- BThe speed of the reaction and the mechanism by which it occurs
- CThe extent to which the reaction will proceed, found from chemical equilibrium
- DThe heat absorbed or evolved when the reaction is carried out at constant pressure
Q2.Thermodynamic data indicate that diamond should convert to graphite, yet the chapter uses this to explain why most people think diamond is forever. The reason is that:
- AThermodynamics actually forbids the conversion at ordinary temperatures
- BThe conversion rate is so slow that the change is not perceptible at all
- CThe conversion needs a catalyst that does not exist in nature
- DGraphite converts back into diamond at exactly the same rate
Q3.In a gaseous reaction the concentrations of the species are expressed as their partial pressures. The units of the rate of such a reaction then become:
- Aatm s^-1
- BL mol^-1 s^-1
- Cmol L^-1 s^-1
- Datm mol^-1 s
