Rate is the dependent variable. [NO] is the controlled variable. Another Example, using the previous reaction and data chart, calculate the rate of the reaction if the NO has a concentration of 0.018 mol/L and H 2 has a concentration of 0.046 mol/L. Method: 1) Use any of the data sets in the chart to calculate k. This is a constant as long as the temp and pressure remain constant. . 2) Use the constant and the new concentration values to calculate the new rate....
