What is the heat of a reaction, in kJ/mol, with a total reaction mixture mass of 62.6 g if the reaction of 0.15 mol of reactant A causes a temperature increase of 4.6 oC in a calorimeter

Explanation:

m = Mass of mixture = 62.6 g

n = Number of mole of reactant = 0.15 mol

= Change in temperature =

c = Specific heat of mixture = (assumed to be the same as water)

Heat generated

Heat of reaction is given by

The heat of the reaction is
