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?

**DrBob222**, Sunday, May 15, 2011 at 12:53pmHere 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.
