Thermochemistry Chapter 6 Tuesday, January 19, 2016 2:49 PM Law of thermodynamics: Energy is conserved; the total energy change in the system and the surroundings is 0.   Euniverse = E system-Esurroundings o System= thing being studied o Surroundings = everything else  qsys= -qsurr Reaction Types  Exothermic Reactions - when the system loses heat energy and work is being done on the surroundings   Esystems less than 0 (negative value)  Esurroundingsreater than 0 (positive value) o If the initial temperature is lower than the final temperature then the reaction is exothermic  Endothermic Reactions - when the system gains heat energy and work is being done on the system   Esystems more than 0 (positive value) Esurroundingsess than 0 (negative value) o If the initial temperature is greater than the final temperature then the reaction is endothermic Work= Force (in Newtons) * distance (in meters)- F*d Pressure= Force / Area - F/A Force= Pressure * Area- F= P*A meaning……. Work (w) = P*A*d Specific Heat Capacity (C s Units= J/ g ̊  the amount of heat energy required to raise the temperature of one gram of a substance 1°C o Intrinsic ability to absorb heat  Molar Heat Capacity Example on how to use Specific Heat Capacity to find the heat of a reaction: mass= 3.10 g T= T f T i-->[37 ̊C-(-8.0 ̊C)]= 45.0 ̊ C sf copper= 0.385 J/g ̊C q= m* C *sT ----> 3.10g(0.385J/g ̊C)(45.0 ̊C)= 53.7 J  Because the result was a positive number the reaction was endothermic More on Work  Work is calculated by multiplying the external pressure by the change in Volume o W= -P* V  As a gas expands the change in Volume will increase but the energy of work will be negative because work is being done by the system on the surroundings. Enthalpy  Sum of the internal energy of a system and the product of pressure and volume o H° reaction n  °fproducts) -  n  °freactants)   means sum  n = coefficient of the reaction  Enthalpy is a state function o State Function = value of the function is dependent on the state of that system; not how it arrived to that state.
