For a process to be at equilibrium, it is necessary that

Question

a)DSsys = DSsurr
b)DSsys = -DSsurr
c)DSsys = 0
d)DSsys = 0 and DSsurr = 0

Answer 1

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

Answer 2

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

Answer 3

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.

Answer 4

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

Answer 5

Thanks Dr.Bob

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