Your favorite snack undoubtedly has a nutrition label that indicates the total number of calories and the number of calories from fat. An analysis was performed as follows to determine the total number of calories in the food. A 0.67g samle of potato chips is burned in a bomb calorimeter whose heat capacity is 2.79 kcal/C. (for each 2.79 kcal of energy given off by the food burned in it, the bomb calorimeter will increase in temperature by 1 C. For the sample given, the temperature of the calorimeter increased from 21.62 C to 22.91 C What is the calorie content of the potato chips in kcal/g? A serving is defined as 1 oz (28g). How many Food calories are concumed in one serving?(note that 1 food calorie is qual to 1 scientific kilocalorie, or 1 Cal=1000 calories)
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
