What factor affects the rate of a chemical reaction? collision frequency orientation of molecules fraction of collisions with sufficient energy All of these
The rate of enzymatic reaction, as for any chemical reaction, depends on temperature. However, the rate abruptly drops above certain temperature, which is different for different enzymes. How would you explain this phenomenon?

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...
