There are several factors that affect the rate of a reaction. These factors include temperature, activation energy, steric factors (orientation), and also collision frequency, which changes with concentration and phase. All the factors that affect reaction rate can be summarized in an equation called the Arrhenius equation: k=Ae−Ea/RT, where k is the rate constant, A is the frequency factor, Ea is the activation energy, R=8.314 J mol−1 K−1 is the gas constant, and T is the absolute temperature. A certain...

A catalyst is a material that affect the rate of chemical reaction, yet emerges unchanged from the reaction. For example, consider the reaction: A + B C + D in which =-kCCB Where B is a catalyst. The reacrion is taking place in a semibatch reactor, in which 100 ft' of a solution containing 2 lb mol/ft of Ais initially present. No B is present initially. Starting at timet 0,5 ft/min of a solution containing 0.5 lb mol/ft of B...
