At high temperatures, elemental Bromine, Br2, dissociates into individual bromine atoms. Suppose that in an experimental 2000°C, it is found that [Br2] = 0.97 M and [Br] = 0.034 M at equilibrium. Calculate the value of K.

At a temperature of 393 k, the temperature of a sample of nitrogen is 1.07 atm what will the pressure be at a temperature of 478 k
