The Delta G formula is: dG = dH - TdS Where all the units remain the same. A chemical reaction can be generally described as Reactants {eq}\leftrightarrow {/eq} Products, where all compounds will have their own values of free energy, enthalpy, and entropy. Delta G will sim...
A Prove a formula with Dirac Delta Why is the Laplacian of ##1/r## in spherical coordinates proportional to Dirac's Delta, namely: ##\left(\frac{\partial^2 }{\partial r^2}+\frac{2}{r}\frac{\partial }{\partial r}\right)\left(\frac{1}{r}\right)=-\frac{\delta(r)}{r^2...
To solve the problem of identifying the reaction for which ΔH ≠ΔE, we need to understand the relationship between enthalpy (ΔH) and internal energy (ΔE) in the context of chemical reactions. Here’s a step-by-step breakdown of the solution: Step 1: Understand the Definitions- ΔH ...
