Re: Why are Mechanisms involving Enzyme/Catalysts Zero Order?

A zero-order reaction means that the reaction's rate is independent on the concentration of reactant/reactants. It makes sense in reactions with enzymes to be zero order because when enzymes are used, the reaction's rate will depend only on the rate at which the enzyme can make the reaction proceed.

Re: steady state vs. equilibrium

I think the main differences are that steady-state is more complicated and assumes that the intermediate concentration is low and constant whereas the pre equilibrium approach is easier to solve but with the restriction that the intermediate concentration has to be at equilibrium

Re: K

I believe only temperature can change the rate constant

deriving how delta G relates to work

whe deriving how delta G is the maximum nonexpansion work that can be done by a system in the textbook, it said that the work for a reversible expansion was -P*delta V. I thought this was for irrevesible expansion only? If it works for reversible expansion as well, then how?

Re: 12.19; find change in pH for weak acids?

How exactly do we find the change in pH if we are not given the initial pH of HCl?

Re: S+ and S- Dipole Moment

You can find which has a greater pull by their electronegativity (the higher the electronegativity, the higher their pull of electrons).
