How do you tell if K >1 given a redox reaction?

If Ecell >0 then K >1. Similarly, if Ecell < 0, then K < 1.

can someone explain why it is important to know whether k is < or > 1.

If Ecell is positive, this means that the redox reaction that favors products are positive. At standard conditions at equilibrium, this would mean K is positive. If equilibrium has not yet been achieved, this means that Q is positive.

If the cell potential is positive then it means the products are favored and therefore K>1 due to [producrs]/[reactants].

I think it is easier to understand it conceptually rather than memorize the numbers. If E is positive, that means that the products are favored, which means that K is also positive.
