In a reaction involving hydrolysis of an organic chloride in presence of large excess of water$RCl + {H_2}O \to ROH + HCl$
Molecularity is $2, $ order of reaction is also $2$
Molecularity is $2$ , order of reaction is $1$
Molecularity is $1$, order of reaction is $ 2$
Molecularity is $1,$ order of reaction is also $ 1$
Assertion : The kinetics of the reaction -
$mA + nB + pC \to m' X + n 'Y + p 'Z$
obey the rate expression as $\frac{{dX}}{{dt}} = k{[A]^m}{[B]^n}$.
Reason : The rate of the reaction does not depend upon the concentration of $C$.
If $‘a’ $ is the initial concentration and $ ‘n’ $ is the order of the reaction and the half life period is $ ‘T’,$ then
Select the rate law that corresponds to the data shown for the following reaction $A+ B\to C$
Expt. No. | $(A)$ | $(B)$ | Initial Rate |
$1$ | $0.012$ | $0.035$ | $0.10$ |
$2$ | $0.024$ | $0.070$ | $0.80$ |
$3$ |
$0.024$ |
$0.035$ | $0.10$ |
$4$ | $0.012$ | $0.070$ | $0.80$ |
Explain order of reaction of complex reaction by giving examples.
The reaction of ozone with oxygen atoms in the presence of chlorine atoms can occur by a two step process shown below
${O_3}(g)\, + \,C{l^ * }(g)\, \to \,{O_2}(g) + Cl{O^ * }(g)$ ..... $(i)$ $[{K_i} = 5.2 \times {10^9}\,\,L\,mo{l^{ - 1}}\,{s^{ - 1}}]$
$Cl{O^ * }(g) + {O^ * }(g)\, \to \,{O_2}(g) + \,C{l^ * }(g)$ ..... $(ii)$ $[{K_{ii}} = 2.6 \times {10^{10}}\,\,L\,mo{l^{ - 1}}\,{s^{ - 1}}]$
The closest rate constant for the overall reaction
${O_3}(g){\mkern 1mu} + {\mkern 1mu} {O^*}(g){\mkern 1mu} \to {\mkern 1mu} 2{O_2}(g)$ is ........... $L\,\,mo{l^{ - 1}}\,{s^{ - 1}}$
