Reactions To this point, material flows have been at steady state (i.e. time was not a variable) Material concentrations often change with time We use rate equations to predict material quantities 2
Reaction Kinetics The speed at which reactions proceedThe rate of reaction (r): the rate of formation or disappearance of a compound-A: the compound of concern in whatever units we like (normally a unit of concentration)-t: time3
