Question

For the following reaction, what volume of NOBr can be produced from 3.8 L of Br2 (measured at the same temperature and pressure), assuming an excess of NO?

2NO(g)+Br2(g)=2NO(Br)2

Answer 1

`7.6LNOBr`

Step-by-step explanation:

Hello,

In this case, since no temperature and pressure are known, one could develop the stoichiometric relationship for 1 mole of
`Br_2` per 2 moles of
`NOBr` in terms of volume as shown below because of the Avogadro's law (change in mole proportional to the change in volume at constant both pressure and temperature):

`3.8LBr_2*(2LNOBr)/(1LBr_2) =7.6LNOBr`

Best regards.
