Consider a reversible elementary aqueous reaction: ? ↔ ?. It is found that the reaction has the standard Gibbs free energy (ΔG°) of -4406 J/mol and standard enthalpy of reaction (ΔHr°) of -41570 J/mol at 25°C. The specific heats (cp )of both A and R are constant over wide range of temperature and the specific heats (cp ) of A and R is 1000 J /mol°C. Note that this is 1st oder reversible reaction and the given initial conditions are: CA0=1 mol/L and CR0=0 mol/L in the feed stream and and FA0=100 mol/min. In kinetic experiment in an isothermal batch reactor, the reaction took 1 min to get 20% conversion at 80°C. The reaction time became 16 min at 20°C to get the same conversion in the same batch reactor. Assuming an Arrhenius temperature dependency of the rate constants, find the reaction rate expression as a function of temperature

Consider a reversible elementary aqueous reaction: ? ↔ ?. It is found that the reaction has the
standard Gibbs free energy (ΔG°) of -4406 J/mol and standard enthalpy
of reaction (ΔHr°) of -41570 J/mol at 25°C. The specific heats (cp )of both A and R are constant over wide range of
temperature and the specific heats (cp ) of A and R is 1000 J /mol°C. Note that this is 1st oder
reversible reaction and the given initial conditions are: CA0=1 mol/L and CR0=0 mol/L in the feed
stream and and FA0=100 mol/min.
In kinetic experiment in an isothermal batch reactor, the reaction took 1 min to get
20% conversion at 80°C. The reaction time became 16 min at 20°C to get the same
conversion in the same batch reactor. Assuming an Arrhenius temperature dependency
of the rate constants, find the reaction rate expression as a function of temperature
