Match the items of Column I with items of Column II

Codes:

When the initial concentration of a reactant is doubled in a reaction, its half-life period is not affected. The order of the reaction will be:
1. 0
2. 1
3. 1.5
4. 2 

The kinetic data for the reaction: 2A + B₂ → 2AB are as given below

The order of reaction with respect to A and B₂ is, respectively:

Match the graph given in Column I with the order of reaction given in Column II.
More than one item in Column I may be linked to the same item in Column II:

Column I		Column II
(i)		(a)	1st order
(ii)		(b)	Zero order
(iii)
(iv)

Select the correct option based on statements below:

For a given reaction the concentration of the reactant plotted against time gave a straight line with negative slope.

The order of the reaction will be:

1. 3                                                      

2. 2

3. 1                                                      

4. 0

A reaction A₂ + B₂ $\to$ 2AB occurs by the following mechanism:

A₂ $\to$ A + A               .....(slow)

A + B₂ $\to$ AB + B       .....(fast)

A + B $\to$ AB               .....(fast)

Its order would be:

1. 3/2

2. 1

3. 0

4. 2

The mechanism of a hypothetical reaction

X₂ + Y₂ → 2XY  is given below: 
(i) X₂ → X + X (Fast)
(ii) X + Y₂  ⇄  XY + Y (slow)
(iii) X + Y → XY (Fast)

The overall order of the reaction will be:

1. 2

2. 0

3. 1.5

4. 1
