This graph shows a plot of the rate of a reaction versus the concentration of the reactant.

b. Make a rough sketch of a plot of [A] versus time

Video transcript

Welcome back everyone in this example, we're told that the graph below shows our reaction rate versus our reactant concentration. We're told that based on this graph, we need to draw a plot of concentration versus time. So based on the graph, given we can see that our concentration of our react in a is increasing of our reaction increases. And based on the concentration of our reactant increasing with the rate of our reaction as seen above. We can say that therefore we have a first order reaction. And so for the next part of this example, they want us to plot concentration versus time in seconds. So we would have the below plot that I'll paste in below. Time is passing on and getting larger. So our concentration of our reactant is decreasing through time and we have to make sure that our plot is curved to show that the concentration is going to continue to decrease until it becomes constant as time passes on. And so for our final answer, it's going to be this entire plot that we have boxed in here. So I hope that everything I explained was clear. If you have any questions, please leave them down below. And I will see everyone in the next practice video
