a) what quantity graphed versus time yields a straight line for a zero-order reaction and what is the equation for the half life time.
b) identify quantity versus time for a first order reaction and equation for half life.
c) same for second order reaction
d) if the initial concentration of a in a first order reaction is 0.0020M and the slope of linear plot is 0.0277M per second calculate the concentration after 25 second.
