______ decilitres = $1$ litre

Q. Rate of a reaction; $A+B\to$ Products; is given below as a function of different initial concentrations of A and B.

[A] mol $litr{e}^{-1}$	[B] mol $litr{e}^{-1}$	Initial rate mol $litr{e}^{-1}tim{e}^{-1}$
0.01	0.01	0.005
0.02	0.01	0.010
0.01	0.02	0.005

The half life of A in the reaction is :

Q. 5 quarters of a litre make 1 litre.

Q. The rate of a reaction between A and B increases by a factor of 1000 times when the concentration of A is changed from 0.1 mole litre${}^{-1}$ to 1 mole litre ${}^{-1}$. The order of the reaction with respect of A is:

Q. Under what conditions will a pure sample of an ideal gas not only exhibit a pressure of 1 atm but also a concentration of $1mollitr{e}^{-1}$?
$[R=0.082$ litre atm $mo{l}^{-1}{K}^{-1}]$
