NOV 2015/11 Q10
A mixture of nitrogen and hydrogen gases, at a temperature of 500 K, was put into an evacuated
vessel of volume 6.0 dm3. The vessel was then sealed.
N2(g) + 3H2(g) 2NH3(g)
The mixture was allowed to reach equilibrium. It was found that 7.2 mol of Nz and 12.0 mol of' Hz
were present in the equilibrium mixture. The value of the equilibrium constant, K., for this
equilibrium is 6.0 x 10-2 at 500K.
What is the concentration of ammonia present in the equilibrium mixture at 500K?
A 0.58 moldm-3
