The synthesis of methanol from carbon monoxide and hydrogen [CO(g) 2H2(g)->CH3OH(g)] is carried out in a continuous vapor-phase reactor at 5.0 atm absolute. The feed contains CO and H2in stoichiometric proportion and enters the reactor at 250C and 5.00 atm at a rate of 21.1 m3/h. The product stream emerges from the reactor at 1270C. The rate of heat transfer from the reactor is 21.0 kW. Calculate the fractional conversion achieved and the volumetric flow rate (m3/h) of the product stream.

Why do the strengths of london (dispersion) forces generally increase with increasing molecular size? choose one: a. heavier atoms have stronger attractions for each other than lighter atoms. b. dispersion forces are all equal in magnitude; there is no size dependence. c. dispersion forces arise from the attraction between the nuclei of atoms, and larger molecules have larger nuclei. d. dispersion forces arise from dipoles caused by the electron distribution being distorted. larger molecules have more electrons and, therefore, more distortions and a bigger force. e. dispersion forces depend on distance. larger molecules are farther apart and so the forces are smaller.
