Question

One mole of nitrogen gas on reaction with $3.01\times {10}^{23}$ molecules of hydrogen gas produces

• A. one mole of ammonia
• B. $2.0\times {10}^{23}$ molecules of ammonia
• C. 2 moles of ammonia
• D. $3.01\times {10}^{23}$ molecules of ammonia

Answer 1

The correct option is B $2.0\times {10}^{23}$ molecules of ammonia

$N_2+3H_2\rightleftharpoons 2N{H}_3$
Initial no. of moles 1 0.5 0
After reaction 1 - 0.167 0.5 - 0.5 0.334 mole
0.334 moles of $N{H}_3=2.0\times {10}^{23}$ molecules
