Question
Nitric Oxide, NO , reacts with hydrogen to give nitrous oxide, N2O, and water.
2NO(g) +H2(g) → N2O(g) + H2O(g)
In a series of experiments, the following initial rates of disappearance of NO
were obtained:
Expriment |
Initial Conc. of NO |
Initial Conc. of H2 |
Initial Rate |
Exp. 1 | 6.4x10-3 M | 2.2x10-3 M | 2.6x10-5 M/s |
Exp. 2 | 12.8x10-3 M | 2.2x10-3 M | 1.0x10-4 M/s |
Exp. 3 | 6.4x10-3 M | 4.5x10-3 M | 5.1x10-5 M/s |
What is the value of the rate constant for the reaction? Express your answer to three significant figures.
Just enter the number (e.g. 2.48x10^-4) and the unit.
