Document Summary
The statements in the following multiple choices deal with the concept of equilibrium. Suppose that the gas-phase reaction a b and b a are both elementary processes with rate constants of 2. 93e-04 s-1 and 2. 12e-03 s-1, respectively. Figure out the value of the equilibrium constant, kp, for the equilibrium a(g) b(g), and figure out which of the two substances, a or b develops higher partial pressure at equilibrium. Choose the correct expression for keq and description (homogeneous or heterogeneous) for the following reaction: No(g) + 1/2 br2(g) nobr(g) is keq = 5. 63e-02 at 230 k. calculate keq for the reaction nobr(g) no(g) + 1/2. Br2(g) at this temperature and figure out whether the equilibrium favors no and. At 1609 k, keq = 1. 48e+00 for the reaction. Gaseous brcl is placed in a closed container at 481 oc, where it partially decomposes to br2 and cl2:
