Asealed container initially contains only 1.0 m gas a and 1.0 m gas b. upon heating the following reaction takes place: a(g) + 2 b(g) ? c(g)+ 2 d(l). after the reaction comes to equilibrium, the concentration of gas c is 0.25 m. what is the equilibrium constant kc for this reaction?

b). the decomposition of n2o4 into no2 has kp = 2. some n2o4 is placed into an empty container, and the partial pressure of no2 at equilibrium is measured to be 0.2 atm. what was the initial pressure in the container prior to decomposition?

c). for the following reaction, find the value of q and predict the direction of change, given that a 1l flask initially contains 2 moles s8, 2 moles sf6, and 2 moles f2.

1/8 s8 (s) + 3 f2 (g) ? sf6 (g) kc = 0.425

d)

a key step in the extraction of iron from its ore is

feo(s) + co(g) ? fe(s) + co2(g) kp =0.403 at 1000°c.

what are the equilibrium partial pressures off carbon monoxide and carbon dioxide when 1.00 atm of carbon monoxide and excess iron(ii) oxide react in a sealed container at 1000°c.

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
