Answer to Question #155034 in General Chemistry for Tim cook

Question

Nitrogen monoxide reacts with hydrogen at elevated temperatures according to the

following equation: 2NO(g)+2H2(g)→ N2(g)+2H2O(g).

Determine the rate law from the following data, and calculate the rate constant for the 

temperature at which these experiments were conducted.

Experiment [NO] (M) [H2] (M) Initial Rate (M/s)

1 5.0 × 10− 3 2.0 × 10− 3 1.30 × 10− 5

2 1.0 × 10− 2

2.0 × 10− 3

5.20 × 10− 5

3 1.0 × 10− 2 4.0 × 10− 3 1.04 × 10− 4

Answer 1

rate constatnt = 250M^-2S^-1
