Which of the following is correct ?
molecularity of a reaction can be fractional
Zero order reaction never stops
A first order reaction must be homogeneous
The rate constant of a reaction becomes equal to the pre-exponential factor when the absolute temperature is infinity
What is molecularity of a relation ? Explain its types by examples.
The following mechanism has been proposed for the reaction of $NO$ with $Br_2$ to form $NOBr$ :
$NO(g) + Br_2 (g) \rightleftharpoons NOBr_2 (g)$
$NOBr_2(g)+ NO(g) \longrightarrow 2NOBr(g)$
If the second step is the rate determining step, the order of the reaction with respect to $NO(g)$ is
In a gaseous reaction
${A_{2\left( g \right)}} \longrightarrow {B_{\left( g \right)}} + \frac{1}{2}\,{C_{\left( g \right)}}$ the increase in pressure from $100\, mm$ to $120\, mm$ is noticed in $5\,\min$. The rate of dissappearence of $A_2$ in $mm\, min^{-1}$ is
For the following reaction scheme (homogeneous), the rate constant has units
$A+B\xrightarrow{K}C$:
For the reaction $A + 2B \to C,$ rate is given by $R$ $ = [A]{[B]^2}$ then the order of the reaction is
