More than one reaction consider the following two gas-phase reactions a+ b= 0 2c=d (a) what are the two equilibrium equations relating the two unknown extents of reaction and the initial gas-phase compositions? you can assume the pressure is low enough that the gases are ideal. (b) what is the equilibrium gas-phase composition at 2.0 atm total pressure given initial gas-phase composition ya = ye = 0.5, y = y = 0, and ki - 1.0. k2 = 2.57 solve the two nonlinear equations numerically. if a computer is not available, you can use trial and error (partial ya - 0.31). (c) what is the equilibrium gas-phase composition at 2.0 atm total pressure given initial gas-phase composition ya - yc = 0.5, y yd 0

Iam in desperate need of with this !

Which actions would increase the rate at salt dissolves in water? stir the water? crush the salt? use less water? heat the water? cool the salt

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent.true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight.a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol
