A liquid-phase chemical reaction with stoichiometry A → B takes place in a semicontinuous reactor. The rate of consumption of A per unit volume of the reactor is given by the first-order rate expression rA(mol/liter·s) = kCA where CA(mol/liter) is the reactant concentration. The tank is initially empty. Beginning at a time t=0, a solution containing A at a concentration CA0(mol/liter) is fed to the tank at a steady rate Ф(liters/s). a. Write differential balances on the total volume of the tank contents, V, and on the moles of A in the tank, nA. Provide initial conditions for each equation. Your equations should contain only the variables nA, V, and t, and the constants Ф and CA0. Simplify the second equation to determine an expression for the steady-state value of nA. b. Integrate each equation to derive expressions for V(t) and nA(t). Use the latter solution to verify the expression for the steady-state value of nA derived in part a.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.

explanation:

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

56 moles of   lieter in chemistry
