Fe(NO3)3 + 3KCNS → Fe(CNS) + 3KNO3 This balanced chemical equation is wrote on the black board when the teacher is going to conduct an experiment on chemical equilibrium.
a. In the above reaction, which chemical has red color.
b. Fe(NO3)3 , KCNS combined together, put it on the test tube stand, is there any col our change? Is the color is diminishing while it kept in test tube stand?
c. Convert the solution reared into four be a kers dilute each with equal amount of water. In the first beaker add Fe(NO3)3 , in the second one KCNS, in the third KNO4 like wise. Compare the color change with the fourth beaker. Find out the reason.
d. Point out the characteristics of equilibrium based on the experiment done.
e. In minute level chemical equilibrium is Kinetic energy why?
f. How and when a reversible reaction attains chemical equilibrium.
g. In the graph given below, when the reactant and product attain the level A? What are the characteristics of the point A?
