Question

Solid carbon and carbon dioxide gas at 1,500 K were placed in arigid 3.00 L container, and the following reaction occured: C(s) +CO2 (g) <--> 2CO (g)
As the reaction proceeded, the total pressure in the container wasmonitored. When equlibrium was reached, there was still some C(s)remaining in the container. Results are recorded below.

Time (hours) Total Pressure of Gases in Container at 1,500K(atm)
0.0 4.00
4.0 6.09
8.0 7.37
10.0 7.37

PLEASE HELP AND ANSWER ALL PARTS IN ENTIRETY!

(a) If a suitable solid catalyst were placed in the reactionvessel, would the final total pressure of the gases at equilibriumbe greater than, less than, or equal to the final total pressure ofthe gases at quilibrium without the catalyst? (i) EXPLAIN! (Assumevolume of solid catalyst is negligible)

(b) In another experiment involving the smae reaction, a rigid 3.00L container contains 10.0 grams of C(s), plus CO (g) and CO2 (g),each at a partial pressure of 3.00 atm at 1,500K. Predict whetherthe partial pressure of CO2 (g) will increase, decrease, or remainthe same as this system approaches equlibrium. Justify theprediction by showing a calculation.
