(a) the above reaction takes place in a batch reactor fitted with a piston such that the pressure inside the reactor remains constant throughout the reaction. the initial volume of the reactor is 2 l. we start out with 2 moles of a, 5 moles of b, and 0 moles of c initially. calculate the following: i) the time it would take to reach a fractional molar conversion fa of 0.80 (i. e. 80% of the initial moles of a have been consumed). ii) the reactor volume when the fraction molar conversion of a is 0.80. iii) concentrations of a, b, and c when the fraction molar conversion of a is 0.80. to get full credit you should clearly state any assumptions you make about the system.
