Laws of thermodynamics apply only when a system is in equilibrium or moves from one equilibrium state to another equilibrium state. In this sixth unit of class 11 chemistry, we answer some of the important questions like: How do we determine the energy changes involved in a chemical reaction/process? Will it occur or not? What drives a chemical reaction/process? To what extent do the chemical reactions proceed? Also, we learn about types of systems, calculate work done, enthalpy & enthalpy change, entropy, spontaneity, and Gibbs free energy.

We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.
