1. The harbour process is used industrially to synthesize ammonia from nitrogen and hydrogen. The thermochemical equation for this is : N2(g) +3H2(g) <-> 2 NH3(g) + 92kJ
a) Use the le chateliers principle to explain why the following changes result in an increase in the yeild of ammonia
i)a decrease in temperature
ii)an increase in pressure
B) even though a reduction in temperature favours the formation of ammonia , describe why, industrially the temperatre of the reactuib chamber is increased.
2. Consider the folliowing reaction: N2(g) + 2O(g)<=> 2NO2 (g)
[n2]= 8.0 mol/l [o2]=2.0 mol/l [NO2]=4.0 mol/l
**Determine the equilibrium constant.
3. Write the equilibrium expressions (K) for each of the following reactions:
i) H2(g)+F2(g) <=> 2NF(g)
ii)4NO(g) +3O2(g)<=> 2N2O5(g)
iii)BaCO3(s)<=>BaO(s)+CO2(g)
The equilibrium constants for three differnet reactionsare
i) Ke= 1.5x10^12
ii)Ke= 0.15
iii)ke=4.3x10^.15
In which reactionis a)The ration the bigest b)smallest
