AIPMT 2003

MCQ (Single Correct Answer)

-1

The temperature dependence of rate constant (k) of a chemical reaction is written in terms of Arrhenius equation, $$k = A \cdot {e^{ - E{}^ * /RT}}$$. Activation energy (E^{$$ * $$}) of the reaction can be calculated by plotting

$$k\,\,vs\,\,T$$

$$k\,\,vs\,\,{1 \over {\log T}}$$

$$\log \,k\,\,vs\,\,{1 \over T}$$

$$\log \,k\,\,vs\,{1 \over {\log T}}$$

-1

The activation energy for a simple chemical reaction A $$\rightleftharpoons$$ B is E_$$a$$ in forward direction.
The activation energy for reverse reaction

is negative of E_$$a$$

is always less than E_$$a$$

can be less than or more than E_$$a$$

is always double of E_$$a$$

MCQ (Single Correct Answer)

-1

2A $$ \to $$ B + C

It would be a zero order reaction when

the rate of reaction is proportional to square of concentration of A

The rate of reaction remains same at any concentration of A

the rate remains unchanged at any concentration of B and C

the rate of reaction doubles if concentrations of B is increased to double.
