Slope = -k

Postby Olivia Young 1A » Wed Mar 06, 2019 6:42 pm

Is there a specific reason both zero order reactions and first order reaction graphs have a slope of -k, while the slope of a second order reaction is k?

This kind of helps answer your question.

I believe it is because of the integrated rate laws derived (specific sign because of the math).

This only means that integrating gives different values, and k would be negative or positive, depending on the equation.
