A person's wound was exposed to some bacteria and then bacterial growth started to happen at the same place. The wound was later treated with...

For $\mathrm{A}_2+\mathrm{B}_2 \rightleftharpoons 2 \mathrm{AB}$ ${{\rm{E}}_{\rm{a}}}$ for forward and backward reaction are 180 and $200\;{\rm{kJ}}\;{\rm{mo}}{{\rm{l}}^{ - 1}}$ respectively If catalyst lowers ${{\rm{E}}_{\rm{a}}}$ for both reaction...

Rate law for a reaction between A and B is given by
${\rm{r}} = {\rm{k}}{[\;{\rm{A}}]^{\rm{n}}}{[\;{\rm{B}}]^{\rm{m}}}$
If concentration of A is doubled and concentration of B...

For bacterial growth in a cell culture, growth law is very similar to the law of radioactive decay. Which of the following graphs is most...

Consider an elementary reaction $\mathrm{A}(\mathrm{g})+\mathrm{B}(\mathrm{g}) \rightarrow \mathrm{C}(\mathrm{g})+\mathrm{D}(\mathrm{g})$ If the volume of reaction mixture is suddenly reduced to $\frac{1}{3}$ of its initial volume, the reaction rate...

In a reaction $A + B \to C$, initial concentrations of A and B are related as ${[A]_0} = 8{[B]_0}$. The half lives of A...

Consider a complex reaction taking place in three steps with rate constants $\mathrm{k}_{1}, \mathrm{k}_{2}$ and $\mathrm{k}_{3}$ respectively. The overall rate constant $k$ is given by...
