Doubling the pressure in a liquid phase reaction:
Correct answer: D. Will not alter the concentration of reactants
- A. Will double the reaction rate
- B. Will increase the reaction rate
- C. Will decrease the reaction rate
- D. Will not alter the concentration of reactants
Explanation
Doubling the pressure in a liquid phase reaction typically does not alter the concentration of the reactants. This is because, in a liquid, the concentration is primarily determined by the solubility of the reactants, which remains fairly constant regardless of pressure changes. Options A, B, and C are incorrect because they assume a direct impact of pressure on reaction rates or concentrations, which is not the case for liquid phase reactions.

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.
