Embibe Experts Solutions for Exercise 2: Assignment

Which of the following statement is incorrect?

For the first order reaction, $\mathrm{A}\left(\mathrm{g}\right)⟶3\mathrm{B}\left(\mathrm{g}\right)+2\mathrm{C}\left(\mathrm{g}\right)$. If initial pressure of $\mathrm{A}$ is ${\mathrm{p}}_0$ and after time $\text{'}\mathrm{t}\text{'}$ from the start of reaction, the total pressure is $\mathrm{p}$, then the rate constant of reaction is given by

A catalyst increases the rate of reaction by

If the rate constant of a reaction is $0.5\times {10}^6{\sec }^{-1}$ at $50 \mathrm{K}$ and $1.5\times {10}^6{\sec }^{-1}$ at $100 \mathrm{K}$. Then the activation energy $\left({\mathrm{E}}_{\mathrm{a}}\right)$ for the reaction is

For effective collisions, the condition(s) to be fulfilled is/are

Select the incorrect statement among the following

If the activation energy of forward and backward reactions in a chemical reaction, $\mathrm{A}⟶\mathrm{B}$ is $15.5$ and $22.7 \mathrm{kJ}{ \mathrm{mol}}^{-1}$ respectively, then select the correct option for the reaction.

For the two first order reactions, rate constants in terms of temperature are given below

$\mathrm{A}⟶\mathrm{P},$  ${\mathrm{k}}_1={10}^{15}{\mathrm{e}}^{\left(\frac{-1500}{\mathrm{T}}\right)}$
$\mathrm{B}⟶\mathrm{Q},$ ${\mathrm{k}}_2={10}^{14}{\mathrm{e}}^{\left(\frac{-1000}{\mathrm{T}}\right)}$

If initially $(\mathrm{t}=0)$, both reaction started with same initial concentration of $\mathrm{A}$ and $\mathrm{B}$, then at what temperature both the reaction will have same initial rate?
