A student has studied the decomposition of a gas $AB _3$ at $25^{\circ} C$. He obtained the following data.
$p ( mm Hg )$ | $50$ | $100$ | $200$ | $400$ |
Relative $t _{1 / 2}( s )$ | $4$ | $2$ | $1$ | $0.5$ |
The order of the reaction is
$0.5$
$2$
$1$
$0$
What is molecularity of a relation ? Explain its types by examples.
An example of a pseudo -unimolecular reaction is
Write unit of rate constant of following reaction :
$1.$ zero order
$2.$ second order
Reaction $aA + bB\,\to $ product. The rate of reaction $= k[A]^3\, [B]^0$ if the concentration of $A$ is double and concentration of $B$ is half the rate will be ?
The rate law of the reaction $A + 2B \to $Product is given by $\frac{{d[dB]}}{{dt}} = k[{B^2}]$. If $ A$ is taken in excess, the order of the reaction will be
