##### Reference no: EM131026921

Acetylene gas, C2H2(g), is used in welding.

(a) Write a balanced equation for the combustion of acetylene gas to CO2(g) and H2O(l).

(b) How much heat is produced in burning 1 mol of C2H2 under standard conditions if both\ reactants and products are brought to 298 K?

(c) What is the maximum amount of useful work that can be accomplished under standard conditions by this reaction?

#### What assumptions must you make in arriving at this estimate

Using data in Appendix C, estimate the temperature at which the free-energy change for the transformation from I2(s) to I2(g) is zero.What assumptions must you make in arriv

#### Estimate the boiling point of benzene

Use a reference source, such as the CRC Handbook of Chemistry and Physics, to find the experimental boiling point of benzene. How do you explain any deviation between your a
