Question

10.
For a chemical reaction A + B + product, the order
is one with respect to each A and B. Value of x
and y from the given data is :-
Rate
[A] [B]
(mol L's)
0.10 10.20M | 0.05 M
0.40
0.05M
0.80 0.40M
(1) 0.20, 0.80
63) 0.80, 0.20
(2) 0.80, 0.40
(4) 0.40, 0.20​

Answer 1

Answer:

In a reaction between A and B, the initial rate of reaction (r0) was measured for different initial concentrations of A and B as given below:

A/ mol L - 1

0.20 0.20 0.40

B/ mol L - 1

0.30 0.10 0.05

r0/ mol L - 1 s - 1

5.07 × 10 - 5

5.07 × 10 - 5

1.43 × 10 - 4

What is the order of the reaction with respect to A and B?

Answer

Let the order of the reaction with respect to A be xand with respect to B be y.

Therefore,
