Hw #8.49 standard state

Postby Hannah Krusenoski 2L » Fri Jan 26, 2018 12:00 am

Why can we assume that the reaction in this question is in its standard state and use 298 K and 8.314 J/Kmol in PV=nRT?

I think that it's just the nature of the textbook that when no explicit information about the conditions is given, it means that the reaction is occurring under standard conditions (298 K for thermodynamics)

We know it is in standard state because all od the reactants and products are given in their standard states, in this case - gases.

Because it doesn't say otherwise and because all the given information assumes a standard state, it is a safe assumption to make.

My TA once said to assume that you're under standard conditions (298K and 1 atm) if the textbook doesn't say what temperature/pressure you're at, so I think you'd just assume that you're at standard state.
