The reaction Aà B is to be carried out isothermally in a constant density batch reactor. Calculate the volume of the reactor (in dm3) needed to decrease the moles of component A from an initial 5 mol to a final 4 mol after 10 hours. You may assume that the reaction rate representing the destruction of A is represented by –rA= k*CA2, where k = 2 dm3/mol* hr. Please express your answer as an integer.
