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:<
To find the internal energy change (ΔU) for the given reaction, we can use the relationship between enthalpy change (ΔH) and internal energy change (ΔU). The formula is: ΔU=ΔH−ΔNgRT Where:-ΔH is the enthalpy change,-ΔN_g is the change in the number of moles of gas,-...

ChemistryCalculating delta H of reaction using bond energies? Hi, I have been stuck for hours, i do not understand how i am supposed to use bond energy values for this question like it asks when bond energy values are for molecules in the gas state. The first molecule reactant is a liqu...
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...
