In the formation reaction of NH3 from N2 and H2, 140 g of N2 40 g and H2 were mixed. Select the option which is correct.

If % yield of reaction is 80 %, then H 2 consumed will be 32 gm.

If % yield of reaction is 80 %, then H 2 consumed will be 32 gm.

Maximum mass of NH 3 which can be formed is 180 gm.

Some N 2 (g) will be left after the reaction.

If NH 3 formed is 85 gm then % yield will be 50 %

If % yield of reaction is 80 %, then H 2 consumed will be 32 gm.

$N_{2} + 3 H_{2} \to 2 {NH}_{3}$

$\begin{array}{l} n = \frac{140}{28} \frac{40}{2} \\ = 520 \end{array}$

$\frac{85}{170} \times 100$

$= 50 %$
