#### Answer

True, K can never be a negative number

#### Work Step by Step

The equilibrium constant can never be a negative number. The expression for the equilibrium constant for the equation A + B => C + D is K = $\frac {[C][D]}{[A][B]}$ Since all the terms are concentrations and a concentration must be either 0 or positive, there is no way that K can ever be negative
