Which of the following reactions will not be affected by increasing the pressure?

Options

A. `PCl_(5)(g) hArr PCl_(3)(g)+Cl_(2)(g)`
B. `N_(2)(g)+O_(2)(g) hArr 2NO(g)`
C. `CaCO_(3)(s) hArr CaO(s)+CO_(2)(g)`
D. `CO(g)+H_(2)O(g) hArr CO_(2)(g)+H_(2)(g)`

Answer

B, D

Explanation

a. `Deltan=1+1-1=1`
b. `Deltan=2-(1+1)=0`
c. `Deltan=1-0=1`
d. `Deltan=1+1-(1+1)=0`
`Deltan` is zero in (b) and (d), so (b) and (d) are not efected by pressure.
