(a)
Interpretation:
When the given LiCl(aq) and AgNO3(aq) pairs of reactants mixed together, how does the contents of beaker look like before and after reaction has to described.
Concept introduction:
Precipitation reaction: The formation of the product is insoluble when the combining two solutions (two mixtures of compounds) are called precipitation reaction.
(b)
Interpretation:
The nanoparticle diagram for the given reaction has to be drawn.
Concept introduction:
Refer to part (a)
(c)
Interpretation:
The chemical equation has to be written.
Concept introduction:
Balanced Chemical equation:
A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.
Balancing the equation:
- There is a Law for conversion of mass in a
chemical reaction i.e., the mass of total amount of the product should be equal to the total mass of the reactants. - First write the skeletal reaction from the given information.
- Then count the number of atoms of each element in reactants as well as products.
- Place suitable coefficients in front of reactants as well as products until the number of atoms on each side (reactants and products) becomes equal.

The dominant macrostate or configuration of a system is the macrostate with the greatest weight W. Are both statements correct?arrow_forwardFor the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forward
