Hi everyone for this problem we want to answer is the following statement true or false, determining the rate constant at various temperatures allows us to derive the activation energy. So if we have values for the rate constant at various temperatures, we can plot that data to get a an equation, a regression line equation. And the way that we can do that is by using the Iranians equation and linear form and that equation is Ln of K. Is equal to negative activation energy over R times one over T plus Ln of A. So what this translates to is Y equals M. X plus B. And because we're plotting that data and we're going to get the Iranians equation and linear form, we will be able to derive the activation energy based off of the data were given for rate constant at various temperatures. Okay, so that's going to make this statement true. That's the answer to this problem. I hope this was helpful.
