In aqueous solution, chlorine dioxide oxidizes iodide ion to iodine and chlorine dioxide is reduced to chlorite ion. 2ClO2 (aq) + 2 I- (aq) ----> 2ClO2- (aq) + I2 (aq) The concentration in molarity, of ClO2 was measured at various time points. The data was plotted and the plot of [1/[ClO2] versus time in seconds was most linear. The linear regression equation for the plot is y= 7.60x10-2 (t) + 2.353. What is the concentration of ClO2 at 2.00 minutes if the initial concentration of ClO4 ia 0.425 M? a.) 0.0872 M b.) 2.50 M c.) 11.5 M d.) 0.399 M

This is second order rate equation with respect to ClO2.
In case of second order, the plot between 1/[ClO2] vs time is a straight line with intercept 1/[ClO2]0 and slope k ( i.e. rate constant)
