Consider the following reaction where kc = 154 at 298 k.2no(g) + br2(g) 2nobr(g)a reaction mixture was found to contain 4.64×10-2 moles of no(g), 4.56×10-2 moles of br2(g) and 0.102 moles of nobr(g), in a 1.00 liter container. is the reaction at equilibrium? if not, what direction must it run in order to reach equilibrium? the reaction quotient, qc, equals .the reactiona. must run in the forward direction to reach equilibrium. b. must run in the reverse direction to reach equilibrium. c. is at equilibrium.

The reaction is not at equilibrium and reaction must run in forward direction.

Explanation:

At the given interval, concentration of NO =

Concentration of =

Concentration of NOBr =

Reaction quotient, , for this reaction =

species inside third bracket represents concentrations at the given interval.

So,

So, the reaction is not at equilibrium.

As therefore reaction must run in forward direction to increase and make it equal to .

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
