Differentiate the enthalpy of a solution with the enthalpy of combustion or a reaction. Also, give the importance of the enthalpy of a solution and why it must be measured.
In an endothermic reaction the enthalpy of the reactants is greater than the enthalpy of the products. In an endothermic reaction, the energy required to break existing bonds is more than the energy released when new bonds form. In an exothermic reaction the energy required to break existing bonds is less than energy released when new bonds form. In an exothermic reaction the potential energy of the reactants is higher than the potential energy of the products and the energy term would be written on the product side of the equation.
In three to five sentences. answer the following auestions. 1. Why is it necessary to indicate the physical state of all reactants and products when giving the enthalpy change for a reaction? 2. The reaction of nitrogen gas and oxygen gas to form nitrogen monoxide, NO, is favored at high temperatures. Thus, NO is found in the exhaust gases of high compression automobile engines since they operate ta high temperatures. Is the reaction endothermic or exothermic? Explain.
In a particular reaction, a coffee cup calorimeter absorbs 487 J of energy while the temperature increases from 24.4 °C to 29.8 °C. How much water was in the calorimeter? Assume the bulk of the solution in the calorimeter was water. 90.2 g 21.6 g 116 g 629 g
For an exothermic reaction, how is the measured temperature change affected if some of the heat produced transfers to the calorimeter? How will the determination of the specific heat of the metal be affected if the thermometer used to record the temperature of the water bath reads too low?
A calorimeter is an insulated device in which a chemical reaction is contained. By measuring the temperature change, AT, we can calculate the heat released or absorbed during the reaction using the following equation: Constants Periodic Table Part A q = specific heat x mass x AT A calorimeter contains 30.0 mL of water at 14.0 °C. When 1.70 g of X (a substance with a molar mass of 76.0 g/mol ) is added, it dissolves via the reaction Or, if the calorimeter has a predetermined heat capacity, C, the equation becomes X(s) + H2O(1)→X(aq) q=C x AT and the temperature of the sblution increases to 30.0 °C At constant pressure, the enthalpy change for the reaction, AH, is equal to the heat, qp; that is, Calculate the enthalpy change, AH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that of water (4.18 J/(g. °C)J, that density of water is 1.00 g/mL, and that no heat is lost to the calorimeter itself, nor to the suroundings.
