If all the n2 and h2 are consumed, what volume of nh3, at the same temperature and pressure, will be produced? at a certain temperature and pressure, 1.9 l of n2 reacts with 5.7 l of h2.

of

Explanation:

First let's write the balanced equation for the reaction :

⇒

By analyzing the coefficients of the reaction we find that the relationship between the compounds is (I)

This means that for example with 1 mole of and with 3 moles of we will obtain 2 moles of

1 mole of gas at STP (Standard Temperature and Pressure) has a volume of 22.4 L

The moles and the volume in liters vary directly therefore we can work with the volume and the relationship (I)

If we divide the volume of and we obtain :

   (II)

The number in (II) satisfies the relationship (I) so we can write in terms of liters that :

With of and of (three times more liters that ) we will produce of (two times more liters that ) satisfying the relationship (I)

the answer is definitely c.
