quiz 1 prep #1: state of PCl3

Postby Ivanna_Tang_3B » Tue Oct 11, 2016 7:52 pm

Hi, how can I tell what the state of the product will be? The problem reads : Solid phosphorus reacts with chlorine gas to produce phosphorus trichloride. I looked it up and the internet says that PCl3 at room temperature is a liquid, but I can't assume that for the reaction, right?
thank you!

I believe you can assume that is the correct state for PCl3. Since it can only take the form of a liquid, that is by definition what state it will be in. Usually, a reaction between a solid and a gas will result in the hydrolysis of one of the elements that will produce a liquid.
