Find the missing number in the series:3, 12, 27, 48, 75, 108, ?
Correct answer: A. 147
- A. 147
- B. 162
- C. 183
- D. 192
Explanation
The pattern of the series is 3 × n², where n is the term number. The terms are 3×1², 3×2², 3×3², and so on. The missing 7th term is 3 × 7² = 3 × 49 = 147.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
