What does r stand for in ideal gas law?

Hey there budd!

This would be known as the gas constant, which play's a huge role in this case. The letter "r" referres to the term Regnault.
This word/term would be a statement in physics and the noting of the pressure of the heat of any source.

Hope this helps you!

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

D. is the answer hope that you
