The correct answers for the problems are below. I am not sure how to work these out so help for these would be great.

1) D

2)B

3)A

4) Delta S is Positive

5) 3*2*463 kj/mol

Consider the following reaction for questions 1-5: 3 Co2 (8)4 H20 ()->GHs(g) + 5 02 (g) If 0.650 moles of CH are formed in a reaction between 1.95 moles of CO2 and 2.95 moles of H2O, identify the limiting reagent in the reaction. а. Ог b. Н.о c. CaH d. CO None- the moles of CO2 and H2O are exactly matched and react completely e. In the reaction above, if 0.650 moles of C;Hs are formed in the reaction, calculate the moles of O2 formed in the reaction? 0.130 moles O a. b. 3.25 moles O2 1.09 moles O c. 0.813 moles O2 d. None of these. e. If the reaction takes place in a 5.00-L reaction vessel at 305K, what will be the combined pressure of the products when the reaction is complete? 19.5 atm а. 0.224 atm 0.174 atm C. d. 16.3 atm e. 18.0 atm If this reaction is stron gly endothermic, estimate the sign of AS°, and then determine which of the following statements is true: AS will be pos itive and AG will be nonextensive under all temperature condition AS° will be positive and AG will only be extensive under high temperature cond itions AS° will be negative and AGo will be nonextensive under all temperature cond itio ns AS will be negative and AG will only be extensive under low temperature cond itions a. b. c. d. AS will be positive and AG° will be exten sive under all temperature conditions. е.
