The gas phase reaction 2AB+C is carried out isothermally in a 38dm3 well-mixed constant volume batch reactor. Pure A at an initial amount of 92moles/dm3 is placed into the reactor. If the rate of destruction of A is given by rA=kCA, with k=0.03min1, determine the concentration of A (in moles/ dm3 ) after 5 minutes. Note that concentration is moles divided by volume. Express your answer to one decimal place
