Explanation The Δ H r x n of a reaction is equal to the difference between the standard enthalpy of the products and the standard enthalpy of the reactants. The Δ H F 0 of the elements in their standard state is 0. Formula used: Δ H r x n =∑n products Δ H p r o d u c t s 0 -∑n reactants Δ H r e a c tan t s 0 where, n products and n reactants are the stoichiometric coefficients of products and reactants respectively. Δ H p r o d u c t s 0 and Δ H r e a c tan t s 0 are the standard enthalpy of the products and reactants respectively. Calculation: 1- Write the balanced equation CH 3 CH 2 OH(l)+3O 2 g)→2CO 2 (g)+3H 2 O(l) 2- Look for the Δ H F 0 from the respective table. Δ H F , C O 2 0 =-393...

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 …

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 energ…

Question

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.
