Question

Using graph paper , use half page graphs to analyze data

Steam and nitrogen gas are produced from nitrogen monoxide and hydrogen gas. Write the balanced equation. Using the data, (a)determine the rate law (orders of the reactants) (b) calculate the rate constant and (c) calculate the rate when nitrogen monoxide concentration is 0.0500M and hydrogen gas concentration is 0.150M.

Balanced equation:

Trial #	Nitrogen monoxide(M)	Hydrogen gas(M)	Initial rate (M/s)
1	0.200	0.200	2.46 x 10 -3
2	0.200	0.400	4.42 x 10 -3
3	0.400	0.200	8.84 x 10 -3

An experiment followed the decomposition of nitrogen dioxide to nitrogen monoxide and oxygen gas. Given the following data, what order is the reaction for nitrogen dioxide? Given a K value of 0.543 M^-1s^-1 and an initial concentration of nitrogen dioxide of 0.0500 M, what is the concentration of this reactant after a half hour? Graph paper is provided.

Time(sec)	[NO2](M)
0.0	0.01000
50.0	0.00787
100.0	0.00649
200.0	0.00481
300.0	0.00380
