For the decomposition of N2O(g)\text{N}_2\text{O}(g) at 700 K700\,\text{K}, log⁡10Kp=−2.35\log_{10}K_p=-2.35 when the equation is written as N2O(g)⇌N2(g)+12O2(g)\text{N}_2\text{O}(g)\rightleftharpoons\text{N}_2(g)+\tfrac12\text{O}_2(g). Calculate log⁡10Kp\log_{10}K_p for the reaction written in the opposite direction at the same temperature.
