WebIf we know the standard state free energy change, G o, for a chemical process at some temperature T, we can calculate the equilibrium constant for the process at that temperature using the relationship between G o and K. Rearrangement gives In this equation: R = 8.314 J mol-1 K-1 or 0.008314 kJ mol-1 K-1. T is the temperature on the Kelvin ... Suppose that infectious individuals make an average of infection-producing contacts per unit time, with a mean infectious period of . Then the basic reproduction number is: where is the rate of contact between susceptible and infected individuals and is the transmissibility, i.e, the probability of infection given a contact.
