Some (CH3)2CHOH is allowed to dissociate into (CH3)2CO and H2 at 452 K. At equilibrium, [(CH3)2CHOH] = 0.218 M, and [(CH3)2CO] = [H2] = 5.11×10-2 M. Additional (CH3)2CO is added so that [(CH3)2CO]new = 9.43×10-2 M and the system is allowed to once again reach equilibrium.
(CH3)2CHOH(g) 7e50f1f7-d29b-4777-b1ee-365a063b4be 8.gif(CH3)2CO(g) + H2(g) K = 1.20×10-2 at 452 K

(a) In which direction will the reaction proceed to reach equilibrium? (to the right/to the left)
(b) What are the new concentrations of reactants and products after the system reaches equilibrium?

1.[(CH3)2CHOH] = M
2.[(CH3)2CO] = M
3.[H2] = M

Problem #3 (ch. 1, problem 15)the ideal gas law provides one way to estimate the pressure exerted by a gas on a container. the law isí‘ťí‘ť=푛푛푛푛푛푛푉푉more accurate estimates can be made with the van der waals equationí‘ťí‘ť=푛푛푛푛푛푛푉푉â’푛푛푟푟â’푞푞푛푛2푉푉2where the term nb is a correction for the volume of the molecules and the term an2/v2is a correction for molecular attractions. the values of a and b depend on the type of gas. the gas constant is r, the absolutetemperature is t, the gas volume is v, and the number of moles of gas molecules is indicated by n. if n = 1 mol of an ideal gas were confined to a volume of v = 22.41 l at a temperature of 0â°c (273.2k), it would exert a pressure of 1 atm. in these units, r = 0.0826.for chlorine gas (cl2), a = 6.49 and b = 0.0562. compare the pressure estimates given by the ideal gas law and the van der waals equation for 1 mol of cl2 in 22.41 l at 273.2 k. what is the main cause of the difference in the two pressure estimates, the molecular volume or the molecular attractions?

Ammonium perchlorate nh4clo4 is the solid rocket fuel used by the u.s. space shuttle. it reacts with itself to produce nitrogen gas n2 , chlorine gas cl2 , oxygen gas o2 , water h2o , and a great deal of energy. what mass of nitrogen gas is produced by the reaction of 2.1g of ammonium perchlorate?
