Textbook Problem 4.43

Postby Emerald Wong 1B » Thu Mar 11, 2021 9:13 am

Hydrogen burns in an atmosphere of bromine gas to give hydrogen bromide gas. (a) What is the standard Gibbs free energy of the reaction H2(g) 1 Br2(g) S 2 HBr(g) at 298 K? (b) If 120. mL of H2 gas at SATP combines with a stoichiometric amount of bro- mine and the resulting hydrogen bromide dissolves to form 150. mL of an aqueous solution, what is the molar concentration of the resulting hydrobromic acid?

I understand the process in solving for this, but the solution manual for part B uses STP instead of SATP. Is this an error? Using SATP would change the answer, so I'm just wondering which conditions would be correct.

Yes, it is an error. You can probably just think of it as STP so you have the same calculations as the manual.

I'm not completely sure but I think it is an error

Does anyone know if we will be tested on the difference in STP and SATP for the final?
