1.	When 0.36 g of glucose was burned in a bomb calorimeter ( Heat capacity `600 JK^(-1)`)the temperature rise by 10 K. Calculate the standard molar enthalpy of combustion (MJ/mole).
Answer» Correct Answer - 3 `C_(6)H_(12)O_(6)(S) + 6O^(2)(g) rarr 6CO^(2) (g) + 6H_(2)O(l)` No. of Mole of `C_(6)H_(12)O_(6) = (0.36)/(180) = 2 xx 10^(-3)`mole `C=(q)/(DeltaT) " " therefore" " q=C xx Delta T = 600 xx 10 J = 6KJ` Heat released per mole `=(6)/(2 xx 10^(-3)) = 3 xx 10^(3)KJ =3MJ` `Delta U =-3ML` `DeltaH = DeltaU + Deltan_(g)RT" " here " " Delta n_(g)=0` `Delta H = DeltaU =-3MJ "mole"^(-1)`
