Question

$2$ mole nitrogen and $6$ mole hydrogen are mixed and heated in $10$ lit vessel. If $1.5$ mole of nitrogen is present in the equilibrium mixture, amount of ammonia in the mixture will be?

• A. $17$ g
• B. $8.5$ g
• C. $1.5$ mol
• D. $3$ mol

Answer 1

The correct option is A $17$ g

solution:

$N_2+2H_2--\to 2N{H}_3$

2 6 0

$2-x$ $6-3x$ $2x$

now $2-x=1.5$

$x=0.5$

now concerntration of ammonia is 1 mole = 17 gram

hence the correct option:A
