Is each of these statements true? If not, explain why.(g) The rate of a reaction increases as the reaction proceeds.
Elina [12.6K]

The rate of a reaction rises as it progresses. The answer is false

<h3>What causes a reaction's rate to increase?</h3>

Generally speaking, raising the temperature of the reaction system, raising the concentration of a reactant in solution, and raising the surface area of a solid reactant will all raise the rate of a reaction. A catalyst can be added to the reaction mixture to speed up a process as well.

As reactants are used up, reactions often get slower with time. Catalysts are substances that, when added to a process, speed it up even if they are not themselves reactants.

Write the chemical equation that represents the process of lattice energy for the case of nacl.
faust18 [17]

Answer: Na^+(g)+Cl^-(g)\rightarrow NaCl(s),\Delta H_{Lattice}=-786kJ/mol

Explanation:

Lattice energy : It is defined energy released when ions combine together in a gaseous phase to form a compound. it is energy possessed by the crystal lattice of a compound. Denoted by symbol \Delta H_{Lattice}.

\Delta H_{Lattice}=positive , energy is absorbed while forming of the lattice

\Delta H_{Lattice}=negative, energy is release while forming of the lattice

Na^+(g)+Cl^-(g)\rightarrow NaCl(s),\Delta H_{Lattice}=-786kJ/mol

One mole of sodium ion when combines with one mole chloride ion release  786 kJ of energy.
