Question

For the chemical reaction A + B C $\to$ E, the rate of the reaction is doubled when the concentration of B was doubled, and when the concentration, of both A and B was doubled rate become doubled and when the concentration of both B and C was doubled rate become quadrupled. What is the order with respect to A, B and C and the total order?

• A. 0, 1, 2; 3
• B. 1, 1, 0; 2
• C. 0, 1, 1; 2
• D. 1, 0, 2; 3

Answer 1

The correct option is C 0, 1, 1; 2

For the chemical reaction A + B C $\to$ E, the rate of the reaction is doubled when the concentration of B was doubled. This indicates that the reaction is of first-order in B. When the concentration, of both A and B, was doubled rate become doubled. This indicates that the reaction is of zero-order in A. When the concentration of both B and C was doubled rate become quadrupled. This indicates that the reaction is of first-order in C.

Total order $=0+1+1=2$

Hence, the order with respect to A, B and C and the total order is
$0,1,1,2$ respectively.

Hence, the correct option is $\text{C}$
