The accompanying figure shows a plot of the logarithm (to the base 10) of the diffusion coefficient versus reciprocal of the absolute temperature for the diffusion of iron in chromium. Determine values for the activation energy and preexponential.
2A(g) + 3B(g) → A2B3(g) If 0.5 atm of gas A is mixed in an evacuated reaction flask with 1.0 atm of gas B, what is the final pressure in the reaction flask? (assume that the reaction goes to completion)
Celsius the initial concentration of the three gases are.3M H 2 S,.3H 2 and .150 S 2 you just need to determine the equilibrium concentrations of all these given 3 gases?
What time will it take 10.0 mL of Chlorine gas to effuse through a porous barrier when it has been noticed that 76.3 min are needed for 10.0 mL of Hydrochloric acid gas to effuse through the same barrier.
Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 9.1 g of octane is mixed with 22.7 g of oxygen.
determined the percent Co by converting your product into a blue-violet colored Co complex and measuring the absorbance in the Spec 20 instrument. What is the formula of this blue-violet complex?
calculate the moles of CO2 you would theoretically expect from 0.203 grams of an alka-seltzer tablet at 700. torr and 285. K.
3.00×10-3 mol of HBr is dissolved in water to make 17.0 L of solution. What is the concentration of hydroxide ions, OH-, in this solution?
plot the titration point. make sure there is enough data. F. what indicator wouldyou use for this titration. what color change would you observe.
the half life increased from 2.0 min to 4.0 min at 25C. Calculate the the order of the reaction and the rate constant.
What force keeps the gases of the earth's atmosphere from diffusing into interplanetary space, where the pressure is essentially zero?
A brewery has a horizontal conveyor belt to transfer malted barley from a storage silo to the mash tun (the large vessel where the malted barley is steeped in hot water).
Explain how FeBr3 assists the reaction. Br2 dissolves in a number of solvents, but we preferentially use glacial acetic acid.
