The rate constant is same for 3 reactions of order I , II and III , respectively, the unit of concentration being in moles per litre. If the concentration of the reactant is unity, the rates of reaction R 1 , R 2 , R 3 will be
Options
- AR 1 = R 2 = R 3
- BR 1 < R 2 < R 3
- CR 1 > R 2 > R 3
- DR 1 = R 2 ≠ R 3
Correct answer
A. R 1 = R 2 = R 3
Step-by-step solution
Suppose R 1 ,   R 2 and R 3 ​ are the rates of three reactions of first, second and third-order, respectively, and k is the rate constant for all three reactions. R 1 = k A   R 2 = k A 2   R 3 = k A 3 A being the concentration of reaction A in mole per litre. Now, R 1 ​ = R 2 ​ = R 3 ​
