I want this solution in C++. 16 LAB: Output a linked list Write a recursive method called printLinkedList() that outputs the integer value of each node in a linked list. Method printLinkedList() has one parameter, the head node of a list. The main program reads the size of the linked list, followed by the values in the list. Assume the linked list has at least 1 node. Ex: If the input of the program is: 5 1 2 3 4 5 The output of the printLinkedList() method is: 1, 2, 3, 4, 5 Hint: Output the value of the current node, then call the printLinkedList() method repeatedly until the end of the list is reached. Refer to the IntNode class to explore any available member methods that can be used for implementing the printLinkedList() method.

The following gas-phase reactions take place in a PFR reactor under isothermal and isobaric conditions. A + 2B \rightarrow D 2D + A \rightarrow E Pure equimolar A and B enters the reactor at 36.0 atm and 227°C and a flow rate of 8.0 L/min The rate of formation of D in the first reaction and the rate of formation of E in the second reaction are respectively: $r_{1D} = k_{1D}C_AC_B$ $r_{2E} = k_{2E}C_AC_D$ Where $k_{1D} = 0.500$ L.mol$^{-1}$.min$^{-1}$, $k_{2E} = 0.200$ L.mol$^{-1}$.min$^{-1}$ a) Clearly show how you developed the design equations into a set of equations that can be solved using Maple. (Provide a sample screen shot of these equations once entered in Maple) b) Plot the molar flows of A, B, D and E as a function of the reactor volume? (Try to plot all molar flows on the same plot using Maple, provide a screen shot of the plot) c) The reagents A and B can easily be separated from the products D and E. However D cannot be separated easily from E. A client orders a product with a minimum ratio of 10/1 of D over E (think in terms of global selectivity). What is the reactor volume required to meet the client's specification at the above conditions. What is the conversion of A under these conditions. (Provide a screen shot of the molar flow values obtained at the selected reactor volume). d) Another client orders a product with a minimum ratio of 10/1 of E over D this time (reverse from the other client). What is the reactor volume required to meet the client's specification under the same conditions. What is the conversion of A under these conditions. (Provide a screen shot of the molar flow values obtained at the selected reactor volume).
