Question

2. The rate of the reaction of nitrogen monoxide with oxygen was measured at 25c starting with various initial concentrations of NO and O2. 2 NO(g) + O2(g) 2 NO2(g) The data collected is summarized in the following table: Trial tcetone HCI 1odime Initial concentration, Initial mol/I reaction rate, NO (g) O2 (g) 0.020 0.010 0.028 0.020 0.0200.057 0.040 0.0200.227 nc. Gr Mexico 76 Hint: for which trials was the concentration of NO changed while [02] remained constant? a. Use the method of initial rates to find the reaction orders with respect to NO and O STA RESTRY TIATIVE ate in 2

Explanation / Answer

from the date

if the concentration of O2 alone doubled    rate also doubled. so first orde with respect to O2.

same way if the concentration of NO alone doubled rate increase two times.   so second order with respect to NO.
