Answer
a. $K = 0.11$
b. $K = 7.6 \times 10^1$
c. $K = 8.8$
d. $K = 1.7 \times 10^{-4}$
Work Step by Step
a. Since the coefficients for that reaction are equal to the half of the coefficients from the first reaction:
$K = \sqrt {1.3 \times 10^{-2}} = 0.11$
b. Since we have inversed the equation:
$K = \frac{1}{1.3 \times 10^{-2}} = 7.6 \times 10^1$
c. Since we have inversed and divided the equation by 2:
$K = \frac{1}{\sqrt {1.3 \times 10^{-2}}} = 8.8$
d, Since we have multiplied the coefficients of the equation by 2:
$K = (1.3 \times 10^{-2})^2 = 1.7 \times 10^{-4}$
