7.8 Reaction between N2 and O2– takes place as follows:
2N2 (g) + O2 (g) 2N2O (g)
If a mixture of 0.482 mol N2 and 0.933 mol of O2 is placed in a 10 L reaction vessel and allowed to form N2O at a temperature for which
Kc= 2.0 × 10–37, determine the composition of the equilibrium mixture.
The value of equilibrium constant i.e. is very small. Therefore, the amount of reacted is also very small. Thus, x can be neglected from the expressions of molar concentrations of . Then,
