Gram mole

The heat of reaction AH is given in joules per gram mole of ammonia formed. Equation 22 ignores the heat of mixing which must be taken into account for apphcation to industrial situations (21,22). The heat evolved in synthesis at 370—540°C is approximately 54,430 kj/mol (23, 400 Btu/lb-mol).

One gram-mole (or pound-mole) is the mass in grams (or pounds) of a given compound that is numerically equal to its molecular weight (M). Thus, the number of pound-moles of a compound contained in a mass of m pounds is m/M.

Given that a metric ton is 1000 kg, determine how much Hg the volcano deposited on every acre of the Yakima Valley, in grams, moles, and number of atoms. 

The reaction is complete within a few minutes at room temperature, and the unmistakable decrease in viscosity may be observed even without resort to quantitative measurement. It is apparent therefore that the polymer contains a minor proportion of head-to-head linkages. The number of such interunit linkages should equal the increase in the number of molecules brought about by the reagent. The increase in the number of molecules per gram mole (44 g.) of structural units is given by... 

For a redox reaction in an electrochemical cell the decrease in free enthalpy (- AG) is in accordance with the energy delivered by the transfer of electrons through an external circuit if this takes place in a reversible way, i.e., at a rate slow enough to allow complete attainment of equilibrium, the conversion of 1 gram mole will deliver an electrical energy of - AG = z FE. In total cell reaction mred, + n ox2 m ox, + nred2, where m81 = nS2 electrons are transfered (<5, and S2 represent the respective valence differences of the two redox systems), we have...

Before terminating the discussion of external mass transfer limitations on catalytic reaction rates, we should note that in the regime where external mass transfer processes limit the reaction rate, the apparent activation energy of the reaction will be quite different from the intrinsic activation energy of the catalytic reaction. In the limit of complete external mass transfer control, the apparent activation energy of the reaction becomes equal to that of the mass transfer coefficient, typically a kilocalorie or so per gram mole. This decrease in activation energy is obviously...
