At 25.0o C, the equilibrium 2 NOBr(g) ¡ê 2 NO(g) + Br2(g) is rapidly established. When 1.10 g of NOBr is placed in a 1.0 L vessel at 25.0o C, the equilibrium pressure is 0.355 bar. Calculate the equilibrium constant K. ( P¥è = 1 bar )

Read your post (as it posted) and tell us what the funny symbols are. P probably means pressure but what is Y with two horizontal lines on the tail of the Y, and e with a backwards accent mark?
