Show that the statement is true. if jk has endpoints j(−4, 1) and k(6, 3), and ln has endpoints l(0, 3) and n(2, 1) then jk and ln have the same midpoint.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
