0.562 g Of graphite is placed in a calorimetr with excess at 25.00° C And 1 atm Pressure.The graphite is ignited and burns completely to from CO2 As shown below C(graphite) + O2 + CO2(g) After than compilation of the reaction,the calorimetr temperature rises to 25.90° C.The heat capacity of the calorimetr is found to be 20.7 KJ/ C. Based on this information calculate the heat of the reaction. a) +18.4 KJ b) +390 KJ c) -18.4 KJ d) -390 KJ
