Velocity constant is the rate of reaction when the concentration of reactants are taken as
Correct answer: C. Unity
- A. Zero
- B. Two
- C. Unity
- D. Three
Explanation
The velocity constant (k) is defined as the rate constant in the rate equation of a reaction. It represents the rate of reaction when the concentration of reactants is taken as unity (1 mole per liter for solutions) under standard conditions. In other words, it is the rate of reaction when the concentration of each reactant is 1 M.

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.
