None of these
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
Reaction rate between two substance $A$ and $B$ is expressed as following $:$ rate $= k[A ]^n[B]^m$ If the concentration of $A$ is doubled and concentration of $B$ is made half of initial concentration, the ratio of the new rate to the earlier rate will be
