The unit of rate constant K is dm3 mol-1 s-1 for a chemical reaction, and the order of the reaction is?
Correct answer: B. 2
- A. 1
- B. 2
- C. 0
- D. 3
Explanation
The formula for finding the order of the reaction isK=(dm3mol-1)^1-n s-1. Where n is the order of the reaction.Option A: For 1st order of the reaction. K=s-1Option B: For 3rd order of the reaction. K=dm6 mol-2 s-1Option C: For zero order of the reaction. K=dm-3 mol+1 s-1Option D: For 2nd order of the reaction.k=dm3 mol-1 s-1

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.
