$4.43 x {10}^{- 5}$
When the reaction is flipped the Kp is reciprocated:$\left(\frac{1}{K p}\right)$ becuase Kp is $- \log \left(\frac{P r o \mathrm{du} c t s}{r e a c \tan t s}\right)$ but if the reaction is flipped reactants become products and so on. Since we have the Kp for the forward we will do $\frac{1}{2.26 x {10}^{4}} = 4.4 x {10}^{-} 5$ This answer makes sense since previously we had a big Kp which means this reaction favors products but when the reaction is flipped the reaction favors the reactants ( what used to be the products) and that's why is it smaller since it favors reactants again recalling that the equilibrium constant is $- \log \left(\frac{P r o \mathrm{du} c t s}{r e a c \tan t s}\right)$ so a favor in reactants will make a large denominator and thus a small fraction
