WebFor a zeroth order reaction: [A] = -kt + [A]0, the y variable is the reactant concentration or [A], the x variable is time or t. If plotting [A] versus t yields a straight line then the reaction is zeroth order. Additionally the slope, m, will be -k and the y-intercept, b, will be the initial concentration of the reactant. WebWith this equation it can be roughly estimated that the rate of reaction increases by a factor of about 2 or 3 for every 10°C rise in temperature.
