Astudent measures the concentration of the product of a reaction over time. which type of graph would best show the change in concentration over time?

line graph
circle graph
box and whisper plot
histogram

The change concentration of the product of a reaction over time is best shown by line graph.

You use the vertical axis (normally y-axis) to show the concentration of the product and the horizontal axis (normally x-axis) to show the time.

In that way the several points may show a tendency that you can show as a line, and the slope of the line is the change of concentration divided by the time.
