Textbook 5H.1a

Postby Nathalia Garibay 1D » Thu Jan 26, 2023 2:50 pm

Hello,

Can someone explain to me how they set up their ice table for this question? I keep getting the wrong answer and I think it has to do with the values I used for my ICE table.

Thanks!

Hi!

You do not need an ICE table for this question. You can write the expressions for K for each new reaction, determine what mathematical operation you need to do to get the new expression, and then do that to 41 (since that is the K they give you for the initial reaction).

In other words, if you multiply your equation by a constant, you will need to raise K to that power to get the K for the new reaction. If the reaction is reversed, then you will need to take the reciprocal of the K that was originally given.

The sections 5H.1 and 5H.2 have very nice explanations for this.

Hope this helps!
