The scatter-plot graph can be used to give a relation between two variables which is Time and Concentration, so the scatter-plot is:
Based on the Plot we can say that there is a negative strong correlation between the variables so, as the time period increases the concentration decreases.

of nitrogen dioxide at 383 °C the concentration of NO2 was followed as a function of time. It was found that a graph of I/[NO2] versus time in seconds gave a straight line with a slope of 0.821 M1 s1 and a y-intercept of 3.46 MM1 Based on this plot, the reaction is order in NO2 and the rate constant for the reaction is In a study of the decomposition of dinitrogen pentoside in carbon tetrachloride solution at 30 "C...
