A sample of air at a certain temperature is contaminated with 2.0 ppm of NO by volume. Under these conditions, the half-life of the reaction has been estimated to be 6.4 103 min. What would the half-life be if the initial concentration of NO were 13 ppm?
Use the Nutritional information on the food bag to calculate the calories per gram? How does this information compare to your information? How do you explain the discrepancy? How could you do the experiment differently to get a more accurate value..
