Which is True $(T)$ and False $(F)$ in the following sentence ?

The reaction is elementary.

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 ?

An elementary reaction between $A$ and $B$ is a second order reaction. Which of the following rate equations must be correct?

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.

The half life for the decomposition of gaseous compound $A$ is $240\,s$ when the gaseous pressure was $500\,Torr$ initially. When the pressure was $250\,Torr$, the half life was found to be $4.0\,min$. The order of the reaction is....... (Nearest integer)

For the reaction ${H_2}(g) + B{r_2}(g) \to 2HBr(g)$, the experimental data suggest, rate $ = K[{H_2}]{[B{r_2}]^{1/2}}$. The molecularity and order of the reaction are respectively
