An electrolytic cell having 100% current efﬁciency, operates at a voltage of 1.9 V when the current is 2.0 kA. Its operating temperature is 86 C. The cell happens to be completely heat insulated: heat can only be removed by the ﬂow of reactants and of products and by water flowing through a cooling system built into the cell. Both feed and cooling water enter the system at 25 C. The cooling water leaves at 80 C. The gases leave at 85 C. Assume that the enthalpy change owing to the reaction is independent of temperature (285.9 MJ per kilomole of water). 1. . "That is the feed water consumption rate? \Vhat is the hydrogen production rate in kg/hour? "That is the ﬂow rate of the cooling water? . A consultant was called in._ and he improved catalysis in the anode reducing the operating voltage (at 2.0 kA) to 1.47.) V The cooling water can now be shut oiT. "That is the. new operating temperature?

Elaborate on the reason(s) that matter is said to move even as in a solid state. select one: a. the particles are bound through intermolecular forces but are able to move past each other with relative freedom. b. the particles have sufficient energy to become an ionized gas and are in the most common state of matter in the universe. c. the particles are not able to move out of their positions relative to one another, but do have small vibrational movements. d. the particles are not bound to one another, move quickly, have a low density, and are able to spread apart from one another if unconstrained.
