Straight-Line Plot for Second-Order Reactions

Postby Annalyn Diaz 1J » Sat Mar 09, 2019 3:06 pm

Why is the straight-line plot for second-order reactions have a positive slope rather than a negative one like zero-order and first-order reactions?

because the integrated 2nd order reaction equation is 1/[A] = kt + 1/[A] where kt is the slope using the equations y = mx + b if mx is a positive then the slope is increasing. The first and zero order have a -kt value in the integrated equation so its slope is negative and is decreasing with time.
