0.562g of graphite kept in a bomb calorimeter in excess of oxygen at 298K,If the heat capacity of the magntude calorimeter and its component is 20.7kj/k,what is the enthalpy change for aabove reaction at 298K and 1atm.
Sir the solution of the above question is given in my book,where I cannot understand why Cv is taken as negative,since according to my opinion it is an endothermic reaction because their is increase in temprature.
