How many moles of Nz, are in a flask with a volume of 350 mL at a pressure of 380.0 kPa and a temperature of 350.0 K?*

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

i think it's c. i'm not sure but i think so.

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042
