Homework Answers
a) by decreasing volume
ofcontainer,pressure
increases.
b) colorless converts into red.
from equation : Dn = nproducts - nreactants
= 1-2
= -1
by increasing pressure equilibrium shifts towards less no of mol
side.so that, here equilibrium shifts
towardsright.gives red
color.

Colorless gas nitric oxide gas, NO, can react with oxygen to form the brown gas nitrogen dioxide, NO2, as shown below: 2 NO(g) + O2(g) → 2 NO2(g). Suppose you wanted to carry out this reaction in the laboratory. You could filled one gas syringe with 100. mL of nitric oxide and another with 111. mL of oxygen gas. When you connected the syringes and mixed the gases, the reaction mixture changes to a brown color indicating the the reaction had...

My question is #2 for the reaction Fe3+ (aq) + SCN- (aq)
FeSCN2+ (aq). The goal is to predict the color change (darker or
lighter) for test tubes 2-8. I have attached the supplemental
sheets given to help with the problem. The test tubes 2-8 are being
manipulated either by temperature or things being added which can
be seen by one of the pictures.
