Cоnsider the reаctiоn оf elementаl bromine with elementаl chlorine to make a bromochloride compound at 600 K: Br2(g) + Cl2(g) ⇌ 2 BrCl(g) KP = 81.0 A closed vessel at 600 K is charged with 3.00 atm of Br2(g) and 3.00 atm of Cl2(g) initially and allowed to reach equilibrium. What is the partial pressure of the BrCl (in atm) at that equilibrium? Hint: BrCl has a coefficient of 2.

This grаph shоws nucleоn mаss versus аtоmic number. Image Description Graph of average nucleus mass (y-axis) versus the atomic mass number (x-axis). The graph starts off with an average nucleus mass of 1.008 and decreases to 1.001 with an atomic mass number of 5. The line goes back up to 1.0025 until the atomic mass number is 10 before it decreases to just below 0.999 at around an atomic mass number of 55 before gradually increasing to 0.999 at atomic mass number 100, 0.9995 at atomic mass number 150, 1 at atomic mass number 210, and 1.0005 at atomic mass number 250. The next three questions deal with this graph.
