Nitric oxide and bromine at initial partial pressures of 98.4 torr and 41.3 torr, respectively, were allowed

Question:

Nitric oxide and bromine at initial partial pressures of 98.4 torr and 41.3 torr, respectively, were allowed to react at 300. K. At equilibrium the total pressure was 110.5 torr. The reaction is 2NO(g) + Br2(g) ⇌ 2NOBr(g)
a. Calculate the value of Kp.
b. What would be the partial pressures of all species if NO and Br2, both at an initial partial pressure of 0.30 atm, were allowed to come to equilibrium at this temperature?
