A mixture of water and graphite is heated to 600K . When the system comes to equilibrium it contains 0.30 mol of H2 , 0.30 mol of CO, 2.3 mol of H2O , and some graphite. Some O2 is added to the system and a spark is applied so that the H2 reacts completely with the O2.Find the amount of CO in the flask when the system returns to equilibrium.
Fortunately, you can narrow the search because the PVC piping comes from unique vendors each with their unique degrees of polymerization. By detailed measurement, you determine that the PVC molecular non-extended (i.e., coiled) length is 7 nm. Wha..
