The following reaction is first order with respect to NO and first order with respect to O2, and the rate constant is 5.0 x 104 M-1s-1:
2NO(g) + O2(g) --> N2O4(g)
Write the rate law for this reaction.
The intial temp of the water is 19.0C and the final temp of the system is 25.1C. The heat loss to calorimeter is negligible. What is the mass of the water?
Determination of the composition of a mixture You will be given a multi-component mixture and will be required to determine (and confirm) the %composition of the mixture, obtain a sample of each component and to verify its purity and identity.
