Question

Part A

What is the reaction order with respect to A?

Part B

What is the reaction order with respect to B?

Part C

What is the reaction order with respect to C?

For the reaction A+B+CD+E, the initial reaction rate was measured for various initial concentrations of reactants. The following data were collected: Trial [A]
(M) [B]
(M) [C]
(M) Initial Rate
(M/s) 1 0.10 0.10 0.10 3.0×105 2 0.10 0.10 0.30 9.0×105 3 0.20 0.10 0.10 1.2×104 4 0.20 0.20 0.10 1.2×104

Part A

What is the reaction order with respect to A?

Part B

What is the reaction order with respect to B?

Part C

What is the reaction order with respect to C?

Explanation / Answer

rate= k [A]x [B]y [C]z

from data table

3.0 x 10^-5 =k [0.1]x [0.1]y [0.1]z ------------->(1)

9.0 x 10^-5 =k [0.1]x [0.1]y [0.3]z ------------->(2)

1.2 x 10^-4 =k [0.2]x [0.1]y [0.1]z ------------->(3)

1.2 x 10^-4 =k [0.2]x [0.2]y [0.1]z ------------->(4)

by solving 1 & 2 , we get

z = 1

by solving 1 & 3 , we get

x = 2

by solving 3 & 4 , we get

y = 0.

rate= k [A]2 [B]0 [C]1

reaction order with respect to A = 2

reaction order with respect to B = 0

reaction order with respect to C = 1
