Chemical reactions encompass changes that only involve the positions of _____ in the forming and breaking of chemical bonds between atoms, with no change to the nuclei, and can often be described by a chemical equation.

Which branch of physical chemistry tell us about the rate of a particular reaction.

For a given reaction $3\mathrm{A}\mathrm{ }+\mathrm{B}\to \mathrm{C}+\mathrm{D}$ the rate of reaction can be represented by

The term $\frac{-\mathrm{dc}}{\mathrm{dt}}$ in a rate equation refers to:

Units of rate of a reaction is $\mathrm{mol} {\mathrm{L}}^{-1}$.

For a given reaction $\mathrm{A} \to \mathrm{B}$, rate of disappearance of $\mathrm{R}$ $= \frac{∆\left[\mathrm{R}\right]}{ ∆\left[\mathrm{t}\right]}$.

Thermal decomposition of ${\mathrm{N}}_2{\mathrm{O}}_5$ occurs as per the equation below :

$2{\mathrm{N}}_2{\mathrm{O}}_5\to 4{\mathrm{NO}}_2+{\mathrm{O}}_2$

The correct statement is

The instantaneous rate of reaction depends on the change in concentration of an infinity small time interval, expressed as the limit or derivation of expression.

The rate of a multistep reaction is determined by the fastest step in the sequence.

The rate of a chemical reaction can be expressed in terms of

Consider the reaction $2\mathrm{NO}\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)⟶2{\mathrm{NO}}_2\left(\mathrm{g}\right)$. If $\frac{\mathrm{d}\left[{\mathrm{NO}}_2\right]}{\mathrm{dt}}=0.052\mathrm{M}/\mathrm{s}$ then $-\frac{\mathrm{d}\left[{\mathrm{O}}_2\right]}{\mathrm{dt}}$ will be 

Consider the reaction, $3{\mathrm{I}}^{-}\left(\mathrm{aq}\right)+{\mathrm{S}}_2{\mathrm{O}}_8^{2-}\to {{\mathrm{I}}_3}^{-}\left(\mathrm{aq}\right)+2{\mathrm{SO}}_4^{2-}\left(\mathrm{aq}\right)$. At a particular time $\mathrm{t}, \frac{\mathrm{d}\left[{\mathrm{SO}}_4^{2-}\right]}{\mathrm{dt}}=2.2\times {10}^{-2}\mathrm{M}/\mathrm{s}.$ What are the values of $\frac{\mathrm{d}\left[{\mathrm{l}}_3^{-}\right]}{\mathrm{dt}}$ at the same time?

The instantaneous rate of reaction $2\mathrm{A}+\mathrm{B}$$\to \mathrm{C}+3\mathrm{D}$ is given by:
