The forward rate of reaction must be the same as the reverse rate of reaction.

In relation to DS, for a process to be at equilibrium should DSsys=DSsurr or DSsys= -DSsurr?

Ginger-May I ask what is this DS you are refering to?

I'm just curious since I've never heard of "DS" in chemistry and I didn't come up with anything on the web.

Christina--DS is delta S (S is entropy), DH is delta H, (H is enthalpy).

  Thanks Dr.Bob
  
  That's what I suspected it was Dr.Bob.
