Consider the following equilibria at temperature 'T' in Kelvin.
2A(g) ⇌ B(g)
2A(g) ⇌ C(g)+D(g)
After the system reaches equilibrium ,it has been found that 20% of initial amount of A has been converted to C and D ,and that 20% of initial amount of A remains. Caculate ,seperately, the number of moles of A,B,C and D and their respective mole fractions at equilubrium if amount of A is 'a' moles.
