The rate of disappearance of $SO_2$ in the reaction,$2SO_2 + O_2 \to 2SO_3$ is $1.28 \times 10^{-5} \ mol \ s^{-1}$. The rate of appearance of $SO_3$ is:

Mention the factors that affect the rate of a chemical reaction.

What is the rate of appearance of $Z$ in the following reaction? $3 X \rightarrow 2 Y + Z$,if the rate of disappearance of $X$ is $0.072 \ mol \ s^{-1}$.

Why does the rate of reaction increase with respect to product?

$NO_2$ required for a reaction is produced by decomposition of $N_2 O_5$ in $CCl_4$ as per the equation $2 \, N_2 O_{5(g)} \rightarrow 4 NO_{2(g)} + O_{2(g)}$. The initial concentration of $N_2 O_5$ is $3 \, mol \, L^{-1}$ and it is $2.75 \, mol \, L^{-1}$ after $30 \, minutes$. The rate of formation of $NO_2$ is $x \times 10^{-3} \, mol \, L^{-1} \, min^{-1}$. The value of $x$ is . . . . . . .

Consider the elementary reaction $A_{(g)} + B_{(g)} \rightarrow C_{(g)} + D_{(g)}$. If the volume of the reaction mixture is suddenly reduced to $\frac{1}{3}$ of its initial volume,the reaction rate will become '$x$' times the original reaction rate. The value of $x$ is:
