Consider the following reaction: AB(s) + C2(g) ⇌ AC(g)  +  BC(g)  +  heat Which of the following statements is false?

Consider the reaction: A(g) ⇌ B(g). The system is at equilibrium at 200°C when the pressure of A(g) is 0.30 atm and the pressure of B(g) is 0.60 atm. If an additional 0 atm of A(g) is added into the reaction vessel, what will be the pressure of B(g) when equilibrium is re-established? Enter your answer numerically to two significant figures.
