Explain the effect on value of `Q_c` by decrease the volume of `CO_((g)) + 3H_(2(g)) hArr CH_(4(g)) + H_2O_((g))` reaction vessel.

Text Solution

Verified by Experts

If the volume is decrease so pressure is increase and gaseous mol decrease (2 out of 4) therefore reaction is forward. To increase the pressure, the partial pressure of reactions `([CO] + [H_2])_((g))` increase and it is in dominator in the formuly of `Q_c` so `Q_c` decreases.
`Q_c=([CH_4][H_2O])/([CO][H_2]^3) gt K`
