A solution calorimeter has a heat capacity

Reference no: EM13256210

A solution calorimeter has a heat capacity of 94.82 J/K. It contains 100mL of a solution that is 3.0 M in H2SO4 and 0.02500 M in Fe2+. This solution has a heat capacity density of 0.232 J/K mL. 0.07900 g of powdered KMnO4 (FW=158.034 g/mol) was introduced into the calorimeter giving a resulting temperature change of +2.44 K. The reaction taking place is:

KMnO4(s) + 5Fe2+ (aq) + 8H+(aq)= Mn2+(aq) + 5Fe3+(aq) + K+(aq) + 4H2O(l)

Determine the standard enthalpy of reaction for this reaction
