Concept explainers
Interpretation:
The enthalpy change for the given reaction is to be calculated with the help of thermochemical data.
Concept introduction:
Hess’s Law states that the change in enthalpy for a
The enthalpy change for a reaction is a state function. It depends upon the initial and final states of the system and not on the path followed.
If any reaction is reversed, then the sign of enthalpy change will also reverse. If enthalpy change is positive, then it will become negative and vice versa.
If any reaction is multiplied or divided any number, then its enthalpy change is also multiply and divides by the same number.

HC2H3O2(l)+2O2(g)2CO2(g)+2H2O(l) The temperature of the calorimeter rose from 25.00C to 35.84C. If the heat capacity of the calorimeter and its contents is 13.43 kJ/C, what is the enthalpy change for the reaction?arrow_forwardThe process of dissolving ammonium nitrate, NH4NO3, in water is an endothermic process. What is the sign of q? If you were to add some ammonium nitrate to water in a flask, would you expect the flask to feel warm or cool?arrow_forward
- The head of a strike anywhere match contains tetraphosphorus trisulfide, P4S3. In an experiment, a student burned this compound in an excess of oxygen and found that it evolved 3651 kJ of heat per mole of P4S3 at a constant pressure of 1 atm. She wrote the following thermochemical equation: P4S3(s)+8O2(g)P4O10(s)+3SO2(g);H=3651kJ Calculate the standard enthalpy of formation of P4S3, using this students result and the following standard enthalpies of formation: P4O10(s), 3009.9 kJ/mol; SO2(g), 296.8 kJ/mol. How does this value compare with the value given in Appendix C?arrow_forwardColorless nitric oxide, NO, combines with oxygen to form nitrogen dioxide, NO2, a brown gas. 2NO(g)+O2(g)2NO2(g);H=114kJ What is the enthalpy change per gram of nitric oxide?arrow_forwardNitrogen gas is confined in a cylinder with a movable piston under a constant pressure of 9.95 104 Pa.
