1.	When 120mg of naphthalene C_(10)H_(8(s)) was burnt in a bomb calorimeter, the temperature rise was 3.05K. Calculate the calorimeter constant and molar standard internal energy change of combustion. Also report by how much will the temperature rise when 100mgof Phenol (C_(6)H_(5)OH_((s))) is burnt in the same calorimeter under the same conditions, if heat liberated is 3962.85J ? (DeltaH_(C)^(@) fo r C_(10)H_(8)=-5157kJ mol^(-1))
Answer» ANSWER :`DeltaH=1585.14JK^(-1),DeltaU=-5152.0kJ MOL^(-1), DeltaT=2.5K;`
