Answer: 6.65*10^-3

Step-by-step explanation:

The reaction below has the products and reactants reversed, so the Kp will be inversed (Kp^-1). The coefficients are also halved, so the Kp^-1 will be to the power of 1/2. This means that the Kp for the reaction below is
(K_p^(-1))^(1/2) =
K_p^{-(1)/(2) } =
(1)/(√(K_p)) =
(1)/(√(2.26*10^4)) = 6.65*10^-3
