Question

Chemistry is my last class then I will officially be a High school graduate. Can some help me with my homework please. I will be going over the lesson as I am waiting for this to get noticed. 1. The concentration in an expression of the equilibrium constant are given in:
Select one:
a. Mol/ml
b g/L
c. gram-equivalents/L
d. Mol/L

Answer 1

f the ____________________ changes, then the equilibrium constant will also change.
Select one:
a. temperature
b. pressure
c. concentration of reactants
d. concentration of products

Answer 2

3. Calculate the equilibrium constant for the following reaction:
CO2(g) + H2(g) ↔ CO(g) + H2O(g)
where:
[CO2] = 0.0954M
[H2] = 0.0454M
[CO] = 0.0046M
[H2O] = 0.0046M
Select one:
a. 4.9 · 10–3
b. 4.9 · 10–2
c. 0.049
d. 2.04 · 102

Answer 3

4. The dynamic part of chemical equilibrium refers to _____________.
Select one:
a. the fact that it is very interesting to observe
b. the changes taking place, even though equilibrium has been reached
c. the one way molecular change of the forward reaction
d. the visible changes occurring as the forward and reverse reaction take place

Answer 4

5.Identify the INCORRECT statement below regarding chemical equilibrium:
Select one:
a. All chemical reactions are, in principle, reversible.
b. To be at equilibrium, the opposing reactions will have equal reaction rates.
c. Equilibrium is achieved when the reactant and product concentrations become equal.
d. Equilibrium is achieved when the concentration of species become constant.

Answer 5

This is too many questions in one post. It really makes you wonder your intentions.

Answer 6

If you have any knowledge of equilibrium already, these questions are easy.

Answer 7

I already took the quiz and passed it. I just like to double check my answers before I turn in a assignment. I posted the questions before over looked the lesson because I know it takes a while to get help on here.
