Question

I would like to know if I'm doing the problems on my Chem II study guide correctly. Here are two images that contain a few questions from my study guide. I would greatly appreciate semi-brief explanations to the questions *UPDATE*  If something in an image isn't readable, try opening the image in a new tab

The following mechanism has been stow OH-+ H+ H2O aS Identify all intermediates included in this mechanism. A) HOI and OH B) H+ only C) H+ and I D) H+ and HOI E) H2O and OH The reaction A + 2B products has the rate law, rate = k [A][B], If the concentration of B is doubled while that of A is unchanged, by what factor will the rate of reaction increase? 15. A) 2 B) 6 D) 8 16. The following three different reactions occur at 500 K. Arrange them in order of increasing tendency (least to greatest) to proceed to completion, that is, to the right-hand side of the chemical equation, at the equilibrium. Kp 1.7 x 102 K,-1.3×10-5 Kg = 5.9 x 10-5 2. A) 2

Explanation / Answer

14, Intermediates are species that are produced and consumed in the reaction mechanism. They are not appear in the actual reaction and in rate law equation.

In the given mechanism, OH- and HOI are produced and consumed. So, these are intermediates.

Answer: A
