homework 8.49

Postby Angela_Kim_1N » Mon Jan 23, 2017 10:52 pm

question:
Oxygen difluoride is a colorless, very poisonous fas that reacts rapidly with water vapor to produce O2, HF, and heat:
OF2 + H2O ---> O2 + 2HF delta H = -318kJ
What is the change in internal energy for the reaction of 1.00 mol OF2?

The solution manual uses 298K as temperature. I was wondering why the temperature is 298. Thank you!

If the temperature isn't explicitly stated, you can assume it's 25°C, which is 298 K.

Is that the ideal T for reactions?
