5g of ethane is confined in a bulb of one litre capacity .The bulb is so weak that it will burst if the pressure exceeds 10 atm. At what temperature will the pressure of gas reach the bursting value ?

pV = nRT
pV `= ("wt. of "C_(2)H_(6))/("mol. Wt. of " C_(2)H_(6)).RT`
`therefore T = (10 xx 1 xx 30)/(0.0821 xx 5)`
= 730.81 K
`= (730.81 - 273)^(@)C`
`= 457.81^(@)C`.
(R = 0.0821 lit. atm/K/mole)
