What is the order of chemical reaction as shown in the bellow figure, if it is found that the reaction rate doubles on doubling the concentration of B and also the reaction rate doubles when the concentrations of both A & B were doubled and quadrupled when the concentrations of both B & C were doubled ?
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
Let the rate be proportional to A^a B^b C^c. Doubling B gives b = 1, doubling A and B together gives a + b = 1 so a = 0, and doubling B and C gives b + c = 2 so c = 1; the total order is therefore 2.
