At 1024 C, the pressure ox oxygen gas from the decomposition of copper(II) oxide (CuO) is 0.49 bar: 4CuO(s) --> 2Cu2O(s) + O2(g). (a) Calculate the fraction of CuO that will decompose if 0.16 mole of it is placed in a 2.0 L flask at 1024 C. (b) What would the fraction be if a 1.0 mole sample of CuO were used? (c) What is the smallest amount of CuO (in moles) that would establish the equilibrium?
A gas cylinder containing 6.38 mol of neon has pressure of 491mmHg at 295k. If 3.22 mol helium is added at constant temp and pressure, what will be the pressure in the cylinder
When maleic acid is heated to about 100C it forms maleic anhydride, however fumaric acid requires a much higher temperature (250-300C) before it dehydrates
A tank of 10 m3 volume contains an ideal gas (CP=30 J/mol-K) at T=298 K and P=5 bar. If gas from the tank is allowed to flow through a reversible device and exhaust to the atmosphere at P=1 bar.
