Embibe Experts Solutions for Exercise 3: Assignment

The reaction $\mathrm{A}⟶\mathrm{B}$ follows first order kinetics. The time taken for $0.80$ mole of A to produce $0.60$ mole of $\mathrm{B}$ is 1 hour. What is the time taken for conversion of $0.90$ mole of $\mathrm{A}$ to produce $0.675$ mole of $\mathrm{B}$?
 

If 

find $\mathrm{B}\%$

The graph between the $\mathrm{logK}$ versus $\frac{1}{\mathrm{T}}$ is a straight line. The slope of the line is

The temperature coefficient for most of the reaction lies between

Which of the following is correct?

The rate constant of a reaction is $1.5\times {10}^7{ \mathrm{s}}^{-1}$ at $50°\mathrm{C}$ and $4.5\times {10}^7{ \mathrm{s}}^{-1}$ at $100°\mathrm{C}$. What is the value of activation energy?

In Arrhenius equation, $\mathrm{k}={\mathrm{Ae}}^{-\frac{{\mathrm{E}}_{\mathrm{a}}}{\mathrm{RT}}},\mathrm{A}$ may not be termed as rate constant

If the rate of reaction increases by 27 times, when temperature is increased by $30 \mathrm{K}$, then temperature coefficient of the reaction is
