Q: It is equal to the enthalpy change minus the temperature times the entropy change. Under standard conditions, it is also equal to negative R T times the natural log of K, where R is the gas law constant, T is the absolute temperature, and K is the equilibrium constant for the reaction; thus a high negative value indicates a forward-going reaction. FTP, identify this quantity, named for a Yale chemist, which is a measure of the spontaneity of a reaction.

Q: This force is represented by a first derivative with respect to position in the harmonic oscillator equation. In one model, this force stems from tiny electrostatic repulsions. It can be understood as the parallel shear component of the contact force, whose other component is typically calculated as mg cosine theta. It is calculated from a coefficient, symbolized mu, multiplied by the normal force. Rolling motion is affected by the "kinetic" type of this force, which is known as "drag" in fluids. For 10 points, name this force that resists the motion of objects against one another.
