The correct representation of an exothermic reaction is:

1.		2.
3.		4.	Both 1 and 2

Rate law for the reaction \(A+2 B \rightarrow C\) is found to be
Rate = k[A][B]
If the concentration of reactant 'B' is doubled, keeping the concentration of A constant, then the value of the rate of the reaction will  be:

An incorrect statement about the collision theory of chemical reaction is:

A first-order reaction is 50 % completed in 1.26 × 10¹⁴ s. The time required for 100 % completion of the reaction will be:

1. 1.26 × 10¹⁵ s

2. 2.52 × 10¹⁴ s

3. 2.52 × 10²⁸ s

4. Infinite

Compounds A and B react according to the following chemical equation.

A(g) + 2B(g) $\stackrel{}{\to }$ 2C(g)

The concentration of either A or B was changed keeping the concentrations of one of the reactants constant and rates were measured as a function of initial concentration. The following results were obtained. Choose the correct option for the rate equations for this reaction.

An incorrect statement regarding a catalyst is:

Consider the reaction A$\to$B. The concentration of both the reactant and the product varies exponentially with time.

The graph that accurately depicts how reactant and product concentrations change with time is:

1.		2.
3.		4.

The graphs that represent a zero-order reaction are:

(a)		(b)
(c)		(d)

The correct graphical representation of first-order reaction is:

(a)		(b)
(c)		(d)

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)
