For the reaction NO+03-->NO2+O2, the reaction was found to be first order both with rspect to NO and O3 (expressing concentrations as molarity) What are the units of the rate constant K for this reaction?
Buffering Action of Proteins, We did this experiment in class but I want to see if the results seem reasonable and, if so, why they were not more varied.
You are given a worked wooden item from an archaeological dig believed to date to during the last glaciation. As such, the artifact would be another piece of evidence.
Compute the difference in pressure between CH4 and an ideal gas if 14.0 moles of gas are in a 6.00 litres tank at the temperature of 21.1 degree celsius . The van der Waals constants for CH4 are a =2.300 L^2 x atm/mol ^2 and b=0.0430 L/mol.
