A 0.213 g sample of solid NH40CONH2 (mw=78.07 g mol¬1) is added to an empty 0.500 L flask. The flask is then sealed and the temperature is kept at 25°C. At this temperature, the solid decomposes as follows: NH,OCONH, (s) = 2 NH, (g) + CO,(g) At equilibrium, some solid still remains, and the total pressure in the flask is 0.14 bar. What is K, at 25°C for this reaction? Choose the closest value. Express all pressures in bar. 4.36 × 10–3 3.29 x 10-1 1.02 × 10¬4 4.07 × 10–4 9.54 × 10¬4
