Thermodynamics And Thermochemistry Neet Previous Year Questions With Definition: thermochemistry is the branch of thermodynamics that studies changes that occur during chemical reactions. thermochemistry chemistry questions with solutions q 1: given that standard molar enthalpies of formation of no(g) and no 2 (g) are respectively 90.3 kj mol and 33.2 kj mol. calculate the enthalpy change for the reaction 2no(g) o 2 (g) →2no 2 (g). Δh° = 27.4 kj mol and Δs° = 29.8 j k. sulfur trioxide (so 3) is produced in large quantities in the industrial synthesis of sulfuric acid. sulfur dioxide is converted to sulfur trioxide by reaction with oxygen gas. write a balanced chemical equation for the reaction of so 2 with o 2 (g) and determine its Δg°.

Class 11 chemical thermodynamics important questions with answers short answer type questions. 1. 18.0 g of water completely vapourises at 100°c and 1 bar pressure and the enthalpy change in the process is 40.79 kj mol –1. A. the solution is at boiling point. (choice b) the solution is undergoing a phase change. b. the solution is undergoing a phase change. (choice c) the velocity of molecules in the solution is increasing. c. Solution: this is a three step process: (1) raise the temperature of the liquid to its boiling point, (2) vaporize the liquid at its boiling point and (3) raise the temperature of the resulting gas to the final temperature. calculate the amount of energy required to heat the liquid from 13.50 oc to 78.40 oc.
