A graph is shown of the pressure of dinitrogen pentoxide, N2O5,  in a reaction vessel during a certain chemical reaction. Match the terms to the closest estimate of the correct value.  Not all numbers will be used.  Hint:  count squares to estimate values.

Consider the reaction of the decomposition of bromochloride to make elemental bromine with elemental chlorine at a particular temperature:                                        2 BrCl(g)   ⇌   Br2(g)  +  Cl2(g)         KP = 81.0 A closed vessel at this temperature is charged with 3.00 atm of BrCl initially and allowed to reach equilibrium. What is the partial pressure of the Br2 (in atm) at that equilibrium?
