I need help with #9

Consider the following reaction and the data from 3 experiments performed at constant temperature Exp # NHA1 NO) Rate of formation of N2 2.0 6.0 2.0 2.0 2.0 6.0 25 1.25 11.25 5. How is the reaction rate expected to change if the concentration of NHe is increased? Increase No Change 6. Based on the given rate of formation of N2(g) in experiment 1, what would be the rate of formation of HzO(U) ? Rate of formation of H-O) 7. What is the value of the reaction order with respect to [NO21? Reaction Order of [NO1 8. If INH41 is zero order, calculate is the value of the rate constant for this reaction. Rate Constant 9. Write the rate law for this reaction. 10. At an increased temperature, the rate constant increases to 12.00. Calculate the rate of reaction at eriment 1 and the rate law you calculated in the this new temperature using the concentrations in exp previous question. Rate of formation of N2 16

Explanation / Answer

As we can see from the data table given:

Changing the conc of NH4+ has no effect on rate of formation of N2. So reaction is zero order with respect to NH4+.

When we triple the conc of NO2-, the rate of formation of N2 increases 9 times. So reaction is second order with respect to NO2-.

Thus the rate law is:

r = k*[NO2-]2
