The reverse water-gas shift (RWGS) reaction is an equimolar reaction between CO2 and H2 to form CO and H2O. Assume CO2 associatively adsorbs to the surface, while H2 dissociatively adsorbs. These adsorption steps are followed by reversible formation of formate (COOH*) and slow dissociation of formate into gaseous CO and adsorbed OH. The adsorbed OH is then removed as gaseous H2O via a hydrogenation step.

a) Using the details of the mechanism listed above, write out the elementary steps for the RWGS reaction.
b) Derive a rate law for the RWGS reaction consistent with the above assumptions and mechanism from (i).
c) Under what conditions is the RWGS reaction first order in CO2?

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.

An inventor claimed that a cyclic engine produces 0.4 kj of work per kj of heat extracted from a heat reservoir. a)- the cycle operates between 380 °c and 25 °c. is the claim valid? b)- if the cycle operates between 380 °c and 125 °c, would the claim be valid?
