Document Summary
What combo of enthalpy and entropy are always spontaneous= free energy has to be neg. , entropy inc, enthalpy decreases. What combo of entropy and enthalpy are always nonspontaneous= Free energy has to be pos, entropy dec, enthalpy inc. If both enthalpy and entropy increase/decrease it can be either depending on how large each number is. Ex: spontaneous @ 100k w/ inc of 200k/cal change in entropy. = 200-(100)(x) x has to be positive in order to make g neg x has to be greater than 2 in order to make g neg. C ex: nonspontaneous @ 100k w/ 2. 5 kcal/ mol change in entropy. += x 250 x has to be positive and greater than 250. Diffusion is spontaneous= mol go downhill energetically (neg change is g)- change in enthalpy. A is more concentrated than b because the mass change is greater. Competitive: inhibitor binds exactly to the active site, turns enzyme off.
