Category: Ch 5 – Chemical Thermodynamics

What is the importance of the topic Thermodynamics? Thermodynamics is the subject which helps in the relation of work, heat, temperature and energy. Studying this topic properly will help students gain overall knowledge. How many laws of Thermodynamics are there in total? There are four laws of thermodynamics.

Given: Aluminium quantity 60.0 g, a temperature increases from 35°C to 55°C, molar heat capacity 24 J mol–1 K–1 Calculate the number of kJ of heat. Given: Equilibrium constant of a reaction is 10, T = 300 K, R = 8.314 JK–1mol–1 Calculate the value of ∆G0? ∆U = 0 for an isolated system, calculate ∆S

Enthalpy change is defined as the change in energy of a system at constant pressure. It is denoted as ΔH. Enthalpy is a state function. Enthalpy change, ∆H = ∆U + ∆ngRT, can be calculated directly from the change in heat at constant pressure, ∆H = qp

Thermodynamics deals with the change of energy in physical and chemical processes. It allows us to study these changes quantitatively as well as to make effective predictions. Therefore, we divide the universe as surrounding and system. Physical or chemical processes lead to progression or immersion of heat part of it may be converted to work.… Continue reading Introduction
