What is the volume of `H_2` produced by the decomposition of 5L of `NH_3` at STP?

Text Solution

Verified by Experts

Let `v _(1) and v _(2)` be the volumes of nitrogen and hydrogen respectively, then
`2 NH _(3) (g) to N _(2) (g) + 3 H _(2) (g) `
`{:(at , t =0, 5L, 0, 0),(at, t =prop, 0, v _(1) L, v _(2) L ):}`
Ratio of volumes of `NH _(3) , N _(2) and H _(2)` is `5 : v _(1) : v _(2) :: 2 : 1 : 3`
Volume of hydrogen , `v _(2) implies (5)/(v _(2)) = (2)/(3) implies v _(2) (15)/(2) = 7. 5 L`
