Question

question 7 (1 point)
when pressure _i_and volume _ii_the reaction in an equilibrium system shifts in
the direction that produces __iii_ particles.
the statement given above is completed by the information given in the row:

row	i	ii	iii
b	increases	decreases	more
c	decreases	increases	less
d	decreases	increases	the same number of
e	increases	decreases	the same number of

○ a
○ b
○ c
○ d
○ e

Explanation:

According to Le Chatelier's principle, when pressure decreases (which is equivalent to volume increasing as \(P=\frac{nRT}{V}\), so lower \(P\) means higher \(V\) at constant \(n\) and \(T\)), the equilibrium shifts in the direction that produces more particles. This is because more particles will increase the pressure (by the ideal gas law \(P = \frac{nRT}{V}\), more \(n\) at constant \(V\) and \(T\) increases \(P\)), counter - acting the decrease in pressure.

Answer:

A. decreases, increases, more
