Explain the following. The value of K (equilibrium constant, rate constant, solubility constant) changes with temperature. But radioactive decay constant is independent of temperature.
Correct Answer: 0
PLACEHOLDER ANSWER - the answer is an explanation. Equilibrium constants, rate constants and solubility products describe chemical processes involving the outer electrons, whose energy changes and activation energies are comparable to thermal energies, so they vary with temperature (van't Hoff and Arrhenius equations). Radioactive decay is a nuclear process governed by the stability of the nucleus, with energies of millions of electron volts. Ordinary thermal energies are far too small to affect the nucleus, so the decay constant does not depend on temperature.
