Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. Annotation "(s)" indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid.
Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [1] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase c {\displaystyle c} : [ 2 ]
Methanol is made from methane (natural gas) in a series of three reactions: Steam reforming CH 4 + H 2 O → CO + 3 H 2 Δ r H = +206 kJ mol −1 Water shift reaction CO + H 2 O → CO 2 + H 2 Δ r H = -41 kJ mol −1 Synthesis 2 H 2 + CO → CH 3 OH Δ r H = -92 kJ mol −1. The methanol thus formed may be converted to gasoline by the Mobil ...
The water in the fuel cell is oxidized to a hydroxy radical via the following reaction: H 2 O → OH• + H + + e −. The hydroxy radical then oxidizes carbon monoxide to produce carbon dioxide, which is released from the surface as a gas: CO + OH• → CO 2 + H + + e −. [16] Using these OH groups in the half reactions, they are also ...
Change in volume with increasing ethanol fraction. The molar volume of a substance i is defined as its molar mass divided by its density ρ i 0: , = For an ideal mixture containing N components, the molar volume of the mixture is the weighted sum of the molar volumes of its individual components.
In thermodynamics, an activity coefficient is a factor used to account for deviation of a mixture of chemical substances from ideal behaviour. [1] In an ideal mixture, the microscopic interactions between each pair of chemical species are the same (or macroscopically equivalent, the enthalpy change of solution and volume variation in mixing is zero) and, as a result, properties of the mixtures ...
where the H 2 O byproduct is recycled via the water-gas shift reaction. CO + H 2 O → CO 2 + H 2. This gives an overall reaction CO + 2 H 2 → CH 3 OH. which is the same as listed above. In a process closely related to methanol production from synthesis gas, a feed of hydrogen and CO 2 can be used directly. [55]
