For the reaction H2(g) + Br2(g) 2HBr(g), Kc = 81.4 at 385ºC. If [H2] = [Br2] = [HBr] = 1.6 × 10–2 M at 385ºC, which one of the following is correct?
Group of answer choices
The reaction is at equilibrium already.
The reaction will proceed in the forward direction because K > 1.
The reaction will proceed in the reverse direction to reach equilibrium because Q < K.
The reaction will proceed in the forward direction to reach equilibrium.
Consider the gas-phase reaction for the synthesis of methanol from
CO and O₂: CO + 2H₂ CH3OH. The value of the equilibrium
constant Kp at 500 K is 6.23 x 10-³. Initially equimolar amounts of
CO and H₂ are introduced into the reaction vessel. Determine the
equilibrium mole fractions at 500 K and 30 bar.
3) An ideal gas consisting of one mole of molecules of type A is in contact with the
surroundings at T=300 K, and under a constant pressure of 1 atm. The gas undergoes a
spontaneous isomeric chemical reaction, wherein some fraction x of molecules of type A
change shape, become isomers of type B. This results in an equilibrium mixture of 1-x moles
of A and x moles of B. The enthalpy of B is lower than the enthalpy of A by 3 kJ/mole, such
that AH = -xɛ; & = 3kJ/mole . The change in entropy is given by
AS ==R(xln x+ (1–x)ln(1– x)).
Use the computer to graph the change in Gibbs free energy as a function of x. Determine, by
inspection of your graph, or otherwise, the concentration of A and the concentration of B
when equilibrium is obtained. What is the maximum work that could be extracted from this
process (aside from PV work)?
