For N2O4(g) ⇌ 2NO2(g), what happens to the forward driving force if the partial pressure of NO2 is increased while temperature stays constant?
A
Q decreases, making ΔG for the forward reaction more negative.
B
Q increases, making ΔG for the forward reaction more positive.
C
K increases immediately, so ΔG° becomes more negative.
D
The reaction must stop because gases cannot affect Q.
