\( 2\mathrm{SO_2}(g) + \mathrm{O_2}(g) \rightleftharpoons 2\mathrm{SO_3}(g) \)
In an equilibrium mixture, the partial pressures are \( P_{\mathrm{SO_3}} = 43 \, \text{kPa} \) ; \( P_{\mathrm{O_2}} = 530 \, \text{Pa} \) and \( P_{\mathrm{SO_2}} = 45 \, \text{kPa} \). The equilibrium constant \( K_p = \) ______ \( \times 10^{-2} \). (Nearest integer)
