The rates of a certain reaction $(dc/dt)$ at different times are as follows

Time                                 Rate (mole $litre^{-1}\,sec^{ -1}$ )

$0$                                        $2.8 \times {10^{ - 2}}$

$10$                                      $2.78 \times {10^{ - 2}}$

$20 $                                     $2.81 \times {10^{ - 2}}$

$30$                                       $2.79 \times {10^{ - 2}}$

The reaction is

A student has studied the decomposition of a gas $AB _3$ at $25^{\circ} C$. He obtained the following data.

The order of the reaction is

The rate of certain reaction depends on concentration according to the equation $\frac{{ - dc}}{{dt}}\, = \,\frac{{{K_1}C}}{{1 + {K_2}C}},$ what is the order, when concentration $(c)$ is very-very high

If the rate of the reaction is equal to the rate constant, the order of the reaction is

Select the incorrect option :

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.
