Question

If you used the method of initial rates to obtain the order for no2, predict what reaction rates you would measure in the beginning of the reaction for initial concentrations of 0.200 m, 0.100 m, & 0.050 m no2.

Answer 1

Answer:

Rate law is: Rate = k[NO2]^2 = 10 x [NO2]^2

When [NO2] = 0.200 M:

Rate = 10 x 0.200^2 = 0.400 M/s

When [NO2] = 0.100 M:

Rate = 10 x 0.100^2 = 0.100 M/s

When [NO2] = 0.050 M:

Rate = 10 x 0.050^2 = 0.0250 M/s
