Pulverized CaCu3 reacts faster because of the increase in:
Correct answer: B. Surface area
- A. Pressure
- B. Surface area
- C. Volume
- D. Surface tension
- E. Temperature
Explanation
The correct answer is option B is the Surface area.In the case of pulverized CaCu3 (calcium carbide), the increased surface area provides more exposed sites for the reaction to occur. Therefore, the increase in surface area is the main factor that contributes to the faster reaction of pulverized CaCu3.

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.
