Question

N 2 (g)+3H 2 (g) <->2NH3(g)
H 2 (g)+l 2 (g) <->2HI(g) a).Which chemical equation has no effect on pressure? b).What is the reason?​

Answer 1

Answer:

H2 + I2 <-> 2HI

Explanation:

because in this equation 2 gas molecules react to make 2 HI molecules

Answer 2

Answer:

a). 2nd eqn has no effect on pressure.

Explanation:

reason is-

In reactant it has 2 molecules which react to form

2 molecules of HI.

and hence there is no effect on pressure.
