Determine the setup and strategy you'd use to solve the following problem. Choose the best description, that best matches your strategy. How many grams of SO3 can be produced by reacting 6.3 grams of SO₂ with oxygen in the synthesis reaction described by the following equation: 2SO2(g) + O2(g) →2SO3(g) (PS - This isn't a trick question. Though it's not easy to measure the mass of a gas, it can be done.) A. Multiply the number of moles given in the problem by Avogadro's number to find grams of SO3. B. One needs to find the molar mass of SO2, the molar mass of SO3, and the mole ratio of SO2 and SO3, and set upa mass-mass stoichiometry solution. C. Multiply the molar mass of oxygen by the number of moles given in the problem. D. Divide 6 moles of SO₂ by the molar volume. 18
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.
