In a galvanic cell, which of the following is true of a tin/copper cell reaction?
K > 1 and standard g > 0
K > 1 and standard g < 0
K < 1 and standard g > 0
K < 1 and standard g < 0
The only way to know this problem is to assume that delta G = 0, so you can set standard g = -RTlnK.
The solution says that a galvanic cell generates power via a spontaneous reaction, so standard G must be less than 0.
What is the relationship between standard G and G at equilibrium?
standard g = -RTlnK
Does this equation always hold true, no matter what?
