Fill in the blanks in the following table for the reaction $\mathrm{X}+\mathrm{Y}\to \mathrm{Z}$ . The reaction is of first order w.r.t. X and zero order w.r.t. Y.

The rate of a gaseous reaction is given by the expression $\mathrm{a}=\mathrm{k}{\left[\mathrm{A}\right]}^2{\left[\mathrm{B}\right]}^3$ . The volume of the reaction vessel is reduced to one half of the initial volume. What will be the reaction rate as compared to the original rate 'a' ?

When a chemical reaction (of order one or more) takes place, during the course of the reaction the rate of reaction

The rate of a chemical reaction involving liquids only will not be influenced by the

Suppose $\mathrm{I}$ is the intensity of absorbed light and concentration of $\mathrm{A}\mathrm{B}$ is $\mathrm{C}\left(\mathrm{M}\right)$, then in the photochemical excitation of $\mathrm{A}\mathrm{B},\mathrm{ }\mathrm{A}\mathrm{B}+\mathrm{h}⟶\mathrm{ }{\mathrm{A}\mathrm{B}}^{\mathrm{*}}$, the rate of excitation of $\mathrm{A}\mathrm{B}$ is proportional to

The rate constant for the reaction, $2{\mathrm{N}}_2{\mathrm{O}}_5\to \mathrm{ }4{\mathrm{N}\mathrm{O}}_2+{\mathrm{O}}_2$ is $3\times {10}^{-5}{\mathrm{s}}^{-1}$. If the rate of reaction is $2.4\mathrm{ }\times \mathrm{ }{10}^{-5}\mathrm{ }\mathrm{m}\mathrm{o}\mathrm{l}\mathrm{ }{\mathrm{L}}^{-1}\mathrm{ }{\mathrm{s}}^{-1}$ , then concentration of ${\mathrm{N}}_2{\mathrm{O}}_5$ is-

For an elementary reaction: $2\mathrm{N}\mathrm{O}\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{N}\mathrm{O}}_2\left(\mathrm{g}\right)$

If the volume of the reaction vessel is reduced to one-third of its original volume, what will be the new rate of the reaction?

The reaction $2A+B+C\to D+E$is found to be first order in A, second in B and zero order in C. What is the effect on the rate of increasing concentration of A, B and C two times?

For a reaction between gaseous compounds,

The reaction rate=k[A][B]. If the volume of the container is made $\frac{1}{4}$ of the initial, then what will be the rate of reaction as compared to the initial rate?

Rate of reaction depends upon

Pieces or chunks of wood burn faster than a log of wood of the same mass because

For the reaction system, $2\mathrm{NO}\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{NO}}_2\left(\mathrm{g}\right)$, volume is suddenly reduced to half its value by increasing the pressure on it. If the reaction is of first-order concerning ${\mathrm{O}}_2$ and second-order concerning $\mathrm{NO}$, the rate of reaction will
