Select the correct statement
Entropy change of all the elementry reactions increases with increases in temperature
Enthalpy change of all the elementry reactions increases with increase in temperature
Rate constant of all the elementry reaction increases with increase in temperature
Activation energy of all the elementry reaction increases with increase in temperature
Assertion :The order of a reaction can have fractional value.
Reason : The order of a reaction cannot be written from balanced equation of a reaction.
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
In a reaction, the concentration of reactant is increased two times and three times then the increases in rate of reaction were four times and nine times respectively, order of reaction is
For a given reaction $t_{1/2} = \frac{1}{k.a}$ the order of reaction will be
An example of a pseudo -unimolecular reaction is
