Question

The tabulated data were collected for this reaction: 2 NO2(g) + F2(g)¡2 NO2F(g) [NO2] (M) [F2] (M) Initial Rate (M, s) 0.100 0.100 0.026 0.200 0.100 0.051 0.200 0.200 0.103 0.400 0.400 0.411 Write an expression for the reaction rate law and calculate the value of the rate

Answer 1

The expression of the reaction rate can be obtained assuming that the reaction follow a linear plot that means follow the equation y = mx + b; where m is the slope, b is the Y intercept and x and y are the variables. In order to obtain the value of the rate (the same value of the slope), we consider the velocities given in M/s and calculate the average as you can see in the image attached. Then, we write the linear plot equation with this value assuming that the Y intercept is with zero.
