Rates of reactions can be determined by monitoring the change in concentration of either reactants or products as a function of time. Is there reaction even if the concentrations do not change? Why or why not?
The reaction A + B --> P at temperature 25°C is the second order reaction with the rate constant k. The initial concentrationsof A and B are [A]0 = 2.0 M and [B]0 = 3.0 M.The rate of the reaction is 1.20 M/s when [A] = 1.0 M.
Estimate the temperature of the exit gas and the rate at which work is done on the gas (i.e the power requirement) for a gas flow of 3.0mol/s.
