Who is Louis Pasteur?

200

It is impossible to construct a system that will operate in a cycle, transferring heat from the low-temperature reservoir to the high-temperature reservoir without any external effect or work interaction with the surrounding.

What is Clausius statement?

200

The transport of mass within a single phase depends directly on the concentration gradient of the transporting species in this phase.

What is interphase mass transfer?

200

This equation mainly is used to characterize the enzymatic rate at different substrate concentrations and the elimination of chemical compounds from the body.

What is Michaelis - Menten equation?

200

I'm bright but I'm not clever. I burn but I'm not a bonfire. I sound like I'm a celebrity but I'm not famous. I twinkle but I'm not an eye. I can be seen at night but I'm not the moon.

Who is Luis Alvarez?

400

It is a measure of how much the chemical potential of the component in the gas deviates from the chemical potential of some reference, namely, the standard state, due to changes in pressure and/or the mole fraction of the component.
