Delta G describes whether or not a reaction is spontaneous. It is sometimes called available energy, because one can think of Gibbs free energy as the amount of usable (or available) energy in a system. Gibbs Free Energy Formula The Formula for Gibbs free energy is as follows: G=...
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:<
Cpds. of formula (I):- (where R1 = 1-4C alkyl; R2 is O or (betaP)(alphaQ), where P is free, esterified or etherified OH and Q is H, alkyl, alkenyl or alkynyl (all =4C); R3 is OH, alkoxy, acyloxy, H, alkyl or acyl) are prepd. by reaction of a cpd. (II), with ...

Delta-Valerolactone, with the chemical formula C5H8O2, has the CAS number 542-28-9. It appears as a colorless liquid with a sweet, fruity odor. The basic structure of delta-Valerolactone consists of a five-membered ring with an oxygen atom and a methyl group attached. This compound is mis...
Chemistry Calculating 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 li...
In this formula, the cross-sections are calculated based on the collision matrix Uab which connects the entrance channel a with exit channels b. When a = n, it means the reaction is neutron incident reaction. The cross-section of the reaction from entrance channel n to exit channel b is ...
