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

Which one of the following equations is correct for the reaction $N_{2(g)} + 3H_{2(g)} \longrightarrow 2NH_{3(g)}$?

What is the rate of disappearance of $B$ in the following reaction? $2A + B \rightarrow 3C$,if the rate of appearance of $C$ is $1.3 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$.

Why is the rate of reaction expressed as negative with respect to a reactant? Is the rate of reaction really negative?

For a chemical reaction $A \rightarrow B$,it was found that the concentration of $B$ increases by $0.2 \, mol \, L^{-1}$ in $30 \, min$. The average rate of the reaction is $...... \times 10^{-1} \, mol \, L^{-1} \, h^{-1}$. (Nearest integer)

The differential rate law for the reaction $H_2 + I_2 \to 2HI$ is:
