The rate of disappearance of $S{O_2}$ in the reaction $2S{O_2} + {O_2} \to 2S{O_3}$ is $1.28 \times {10^{ - 3}}g/sec$ then the rate of formation of $S{O_3}$ is

$A $ gaseous hypothetical chemical equation $2A$ $ \rightleftharpoons  $ $4B + C$ is carried out in a closed vessel. The concentration of $ B$  is found to increase by $5 \times {10^{ - 3}}mol\,\,{l^{ - 1}}$ in $10 $ second. The rate of appearance of $B$  is

The rate law for the reaction  Sucrose + Water $\xrightarrow{{[{H^ + }]}}$ Glucose + Fructose is given by

By “the overall order of a reaction”, we mean

Which of the following reaction will have fractional order for $A_2$ or $B_2$ ?

For the reaction $A + B \rightarrow$ products, it is observed that

$(i)\,\,$on doubling the initial concentration of $A$ only, the rate of reaction is also doubled and

$(ii)$  on doubling the initial concentration of both $A$ and $B,$ there is a change by a factor of $8$ in the rate of the reaction.

The rate of this reaction is given by
