4. 100 moles of ethane ($C_2H_6$) react to form ethylene ($C_2H_4$) and hydrogen gas ($H_2$). However, some ethylene reacts with ethane to form propylene ($C_3H_6$) and methane ($CH_4$). If the fractional conversion of ethane is 0.70 and the selectivity of ethylene to propylene is 5, find the molar composition (mole fractions) of the product gas 10 points $C_2H_6 \to C_2H_4 + H_2$ $C_2H_6 + C_2H_4 \to C_3H_6 + CH_4$
