You can speed up a reaction by:
Correct answer: C. Using more concentrated solution
- A. Using less concentrated solution
- B. By lowering the temperature
- C. Using more concentrated solution
- D. Stopping stirring
Explanation
A more concentrated solution has a higher number of reactant particles in the same volume. This higher concentration means there are more collisions between particles, increasing the likelihood of successful collisions and speeding up the reaction rate.

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.
