No, writing $\hat{H}'\psi_3^{(0)} = E_3^{(1)} \psi_3^{(0)}$ will be incorrect. I will give you two explanations for the same, one intuitive and other mathematical. Intuitive Explanation: Assuming ...

It seems like you are just being introduced to quantum mechanics and is confused with the concept of exchange energy. The concept can be confusing at first, since it neither involves exchanging ...

The reason might be that while drawing the reaction energy profile, we forget to mention what energy we are mentioning in the Y-axis. The following conventions are generally used: If reaction ...

this is an interesting question and I will answer it a bit differently. There is a well known analysis technique in materials chemistry called ICP-MS (Inductively Coupled Plasma Mass Spectrometry) ...

$K_\mathrm{a}$ is the measurement of equilibrium constant when an acid dissociates as: $$\ce{HA <=> H+ + A-}$$ $$K_\mathrm{a} = \frac{[\ce{H+}][\ce{A-}]}{[\ce{HA}]}$$ The term $\mathrm{p}K_\... View answer 0 votes First of all, I would like to thank @john for the question. Though this looks like a homework question, but this question actually tests the principles of quantum mechanics we understand in atomic ... View answer Accepted answer 2 votes Thank you for the question. This is a very basic physical chemistry question but the way it has been asked is interesting. In order to understand the probability of displacement of a H from any X-H ... View answer 4 votes First if all, I appreciate you and thank you for putting up such a good question. One thing I will request you to note here is the definition of temperature. Temperature, in broad sense, is defined ... View answer Accepted answer 1 votes Let me put it this way: Every compound exist in a 3N dimensional configuration space (may be simple XYZ coordinates of the system, may be internal coordinates, based on your choice), and based on the ... View answer Accepted answer 2 votes For GAMESS, the command is not$\$STATTP$, but it is $\$STATPT$. Also, please change the commas to dot, otherwise it considers it to be a part of the number. Please refer to the GAMESS manual for ... View answer Accepted answer 1 votes From the ideal gas equation, we get $$PV=nRT \implies P=\frac{n}{V}RT=cRT$$ where$c$represents the concentration. Consider an arbitrary reaction $$n_AA\rightarrow n_BB$$$$K_c=\frac{c_B^{n_B}}{c_A^... View answer 1 votes The excitation of electrons are caused by photons while their de-excitation is causes the emission of photons of the same energy as the energy differemce between two states. The general expression for ... View answer Accepted answer 0 votes The concept of Ferromagnetism, Paramagnetism and Diamagnetism is completely different, though they all show magnetic properties. FERROMAGNETISM: This is constituted of domain and each domain contains ... View answer 6 votes Consider this structure of purine: The ring on the left contains two nitrogen heteroatoms and is aromatic due to π electron conjugation. Having six π electrons, it obeys Hückel's rule. For the ring ... View answer 1 votes I think$\ce{BaCl2}$should be added later. This is because$\ce{BaCl2}$is soluble in water, but the metal sulphate you will be given may not be soluble. So if you add$\ce{M2SO4}\$ later, you may get ...
