PART: The scenes below show two experiments at a given temperature and volume involving reactants X (black) and Y (gree):

If the rate law for the reaction is rate = k[X]2 what is the initial rate of experiment 2 given that the rate of experiment 1 is 0.50 M/s Part 2:

At a particular temperature and volume, two gases, A (red) and B (blue), react. The following molecular scenes represent starting mixtures for four experiments:

Reaction order with respect to A?

Reaction order with respect to B?

Overall order of the reaction

What is value of k? enter a number to 2 decimal places e.g. 1.23e-4

Part 3:

Find the rate law, the individual and overall reaction orders, and the average value of k for the reaction

H2 + I2 ? 2HI, using the following data at 450?C:

Exp	initial rate (M/s)	initial H2 (M)	initial I2 (M)
1	1.9x10-23	0.0113	0.0011
2	1.1x10-22	0.0220	0.0033
3	9.3x10-23	0.0550	0.0011
4	1.9x10-22	0.0220	0.0056
