Question

Rate is expressed in $mol{L}^{-1}mi{n}^{-1}$
In the above reaction, the order is

	$A+B\to C$
	[A]	[B]	[C]
1	$1.0$	1.0	$0.25$
2	$2.0$	1.0	$0.50$
3	$1.0$	2.0	$0.25$

• A. Zero in A and one in B
• B. One in A and zero in B
• C. One in both A and B
• D. Zero in both A and B

Answer 1

The correct option is B One in A and zero in B

In experiment (1) and (3), [A] is constant and [B] becomes double, but rate does not change, so order w.r.t B = 0.
In experiment (1) and (2), [B] is constant and [A] is doubled and the rate also is doubled. So order w.r.t. [A] = 1.
