Equilibrium and Change in Pressure

NOBr in a 1.1 g quantity is placed in an evacuated 1 liter flask at -55 degrees C. The flask is warmed to 0 degrees C where the gaseous contents exert a pressure of 0.3 atm (all species are gaseous). At 25 degrees C, the equilibrium total pressure rises to 0.35 atm. What is Kp at 0 degrees C and 25 degrees C? What is delta H (assume enthalpy is temperature independent)?
