2 NO(g) + 2 H2(g) > N2(g) + 2 H2O(g)
Reactant Concentration(mol/L) and
Rate of Appearance of N2
[NO] [H2] (mol/L·s)
0.420 0.122 0.136
0.210 0.122 0.0339
0.210 0.244 0.0678
0.105 0.488 0.0339
What is the rate constant?

Here is what you need to do.
1. Determine order for NO.
2. Determine order for H2.
3. Determine k
rate = k(NO)^x(H2)^y
For the order of NO, divide equation 1 by 2. I get the order to be 2 for NO.
For the order of H2, divide equation 2 by 3. I get the order to be 1 for H2.
3. Use any equation, substitute rate, (NO) and (H2) and solve for k.
