Dinitrogen pentoxide decomposes in chloroform as a solvent to yield nitrogen dioxide and oxygen gas. The decomposition is first order with a rate constant of 1.0 x 10-5 s-1 at 45 degrees Celsius. Calculate the partial pressure of oxygen produced from 1.00L of 0.600M dinitrogen pentoxide solution at 45 degrees celsius over a period of 20.0hours if the gas is collected in 10.0L container. (Assume that the products do not dissolve in chloroform.)
The tank is first evacuated, and then it is connected to a 50.0 L cylinder of compressed nitrogen gas. The gas pressure in the cylinder, originally at 21.5 atm, falls to 1.55 atm without a change in temperature. What is the volume of the tank?
A bicycle tire is filled with air to a pressure of 100. psi at a temperature of 19 degrees celcius. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58 degrees celcius.
given that Go = 5.02 kcal/mol for the complete reaction catalyzed by isocitrate dehydrogenase and that Go = 4.71 kcal/mol for the nonoxidative decarboxylation of oxalosuccinate, oxalosuccinate + H+ ----> CO2 + a-ketoglutartate.
A gas occupies 22.4 L at STP and 14.5L at 100 C and 2.00 atm pressure. how many moles of gas did the system gain or lose?
