One mole of a reactant reacts with a rate of 0.6 mol dm-1s-1. What is the rate constant of this reaction if reaction is first order?
Correct answer: C. 0.6 s-1
- A. 1s-1
- B. 0.3 s-1
- C. 0.6 s-1
- D. 0.9 s-1
Explanation
The constant which defines the relationship between the molar concentration of the reactants and the rate of the chemical reaction is known as the rate constant. The rate constant is symbolized as k .Rate = -d[A]/dt = k[A]1 = k[A]So basically, it will be the same as we can see that reactant is 1 mole, so the rate constant will be 0.6 as reaction is first order

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.
