Equilibrium constant K is related to E c e l l o and not E c e l l because

Options

  1. AE c e l l o is easier to measure than E c e l l
  2. BE c e l l becomes zero at equilibrium point but E c e l l o remains constant under all conditions
  3. Cat a given temperature, E c e l l changes hence value of K can not be measured
  4. Dany of the terms E c e l l or E c e l l o can be used

Correct answer

B. E c e l l becomes zero at equilibrium point but E c e l l o remains constant under all conditions

Step-by-step solution

At equilibrium, E c e l l becomes zero which means no current is generated by the cell at this point. E c e l l o remains constant hence equilibrium constant is related to E c e l l o .
