dx/dt is rate of reaction expression where dx is ?
Correct answer: C. Very small change in concentration
- A. Concentration
- B. Change in concentration
- C. Very small change in concentration
- D. All of these
Explanation
The correct answer is C) Very small change in concentration, as "dx" represents a very small change in concentration during an infinitesimally small time interval (dt) in the rate of reaction expression dx/dt.

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.
