Equilibrium
which of the following reactions is not reversible? - correct answerfrying an egg
which statement about a chemical equilibrium is correct? - correct answerforward and
reverse reactions happen at equal rates
looking at the screen, how do the concentrations of reactants and products change over
time at equilibrium? - correct answerThe concentrations of NO2 and N2O4 stay the
same
for our equilibrium, Kc was calculated to be 4.6×10^-3 how did the current conditions.
What does this imply for the concentrations of NO2 and N2O4? if you click on view
image you can have a look at the cheat sheet containing the relevant equations. -
correct answer[N2O4]>[NO2]
what happens when you put the syringe into liquid nitrogen? Explore to retry the
experiment - correct answermost of the NO2 is converted to N2O4
what color did you predict for the syringe inside the liquid nitrogen tank? have a look at
the graphs on the screen to answer the question - correct answertransparent
which statement below is true of Kc's value at -196C? click on view image to use the
cheat sheet - correct answerKc << 1
what happens when we let the mixture heat up to room temperature again - correct
answerN2O4 is converted back to NO2
what happens when you put the syringe into boiling water? Cook explore to try the
experiment and generate new data on the screen if you wish - correct answermost of
the N2O4 is converted to NO2
now I think about the opposite case to our experiment, and exothermic reaction.
Chatelier's principle can help here again. How do you think the equilibrium is affected by
an increase in temperature? - correct answerThe equilibrium is shifted to the left
what is the value of Kc in boiling water? - correct answerKc >> 1
which reaction is favored when we let the syringe cool down to room temperature
again? - correct answer2 NO2(g) -> N2O4(g)
