The reactions are carried out at 310°c and 4 bar pressure using a catalyst and air as an oxidant. steam is added in the ratio 8: 1 steam to propylene to stabilize the heat of reaction. if 50% excess air is used (sufficient air so that 50% more oxygen is present than is needed for all the propylene to react by the first reaction), calculate the equilibrium composition of the reactor effluent.
hi my dear friend,
changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing. when steam, which is gaseous water, condenses, heat is released. likewise when liquid water freezes, heat is given off. in fact heat must be continually removed from the freezing water or the freezing process will stop.
here's a clue: metals are great electrical conductors and non-metals, especially the noble gases at the very right of the period table, barely reacts (because they have a full valence shell).
