What volume of hydrogen will be produced if 100cm3 of ammonia is completely decomposed at constant temperature and pressure? The equation for the reaction is 2NH3(g) → N2(g) + 3H2(g)

A.

50cm3

B.

150cm3

C.

200cm3

D.

300cm3

View answer & explanation

Correct answer is B

According to the equation 2NH3 → N2 + 3H2 2x22400cm 3 of ammonia will produce 3x22400cm 3 of hydrogen if 100cm3 of NH3 is used H2 volume = 100/2x22400 x 3 x22400 = 150cm3
