12. Consider the following reaction. CH3CH,Br + H2O CH3CH2OH + HBr (c) Calculate the enthalpy of the reactiorn (d) Is the reaction endothermic or exothermic.
500.0 mL of 0.100 mol·L HCl(aq) was added to a high quality insulated calorimeter containing 500.0 mL of 0.100 mol·LNaOH(aq). Both solutions had a density of 1.000 g·mL and a specific heat of 4.184 J·g ·K . The calorimeter had a heatcapacity of 850.0 J·K . The temperature of the entire system rose from 25.50 C to 26.05 C.Calculate the heat of reaction. Thank you!
