Question 1: Palette 1/5

AIIMS 2019 MCQ

Find out time period of Ist order reaction. When reaction complete $2 / 3 \mathrm{rd}$. If the value of rate constant is $4.3 \times 10^{-4}$

$0.0025 \times 10^3 \mathrm{~sec}$

$0.25 \times 10^3 \mathrm{~sec}$

$0.025 \times 10^3 \mathrm{~sec}$

$2.5 \times 10^3 \mathrm{~sec}$

Question 2: Palette 2/5

AIIMS 2019 MCQ

What is the activation energy $(\mathrm{kJ} / \mathrm{mol})$ for a reaction if its rate constant doubles when the temperature is raised from $300 \mathrm{~K}$ to $400 \mathrm{~K}$ of these $(R=8.314 \mathrm{~Jmol}^{-1} \mathrm{~K}^{-1})$

68.8

6.88

Question 3: Palette 3/5

AIIMS 2018 MCQ

Among the following statements, the correct statement about the half-life period for a first order reaction is

independent of concentration

proportional to concentration

inversely proportional to concentration

inversely proportional to the square of the concentration

Question 4: Palette 4/5

AIIMS 2018 MCQ

The rate constant for the first order decomposition of a certain reaction is described by the equation $\ln k\left(\mathrm{~s}^{-1}\right)=14.34-\frac{1.25 \times 10^4 \mathrm{~K}}{T}$. The energy of activation for this reaction is

$1.26 \times 10^4 \mathrm{~cal} \mathrm{~mol}^{-1}$

$4.29 \times 10^4 \mathrm{~cal} \mathrm{~mol}^{-1}$

$3.12 \times 10^4 \mathrm{~cal} \mathrm{~mol}^{-1}$

$2.50 \times 10^4 \mathrm{~cal} \mathrm{~mol}^{-1}$

Question 5: Palette 5/5

AIIMS 2018 MCQ

Assertion (A) The reaction

$\begin{aligned} 2 \mathrm{NO}+\mathrm{O}_2 & \longrightarrow 2 \mathrm{NO}_2 \\ \text { and } \quad 2 \mathrm{CO}+\mathrm{O}_2 & \longrightarrow 2 \mathrm{CO}_2 \end{aligned}$

proceeds at the same rate because they are similar.

Reason (R) Both the reactions have same activation energy.

Both (A) and (R) are true and (R) is the correct explanation of (A).

Both (A) and (R) are true, but (R) is not the correct explanation of (A).

(A) is true and (R) is false.

Both (A) and (R) are false.
