The following is known as the thermite reaction: 2Al(s)+Fe2O3(s)→Al2O3(s)+2Fe(s) This highly exothermic reaction is used for wel
Colt1911 [192]

Answer:

\Delta H_{rxn}=-847.6\ KJ/mol.

Explanation:

The balanced chemical equation is:

2Al(s)+Fe_2O_3(s)-->Al_2O_3+2Fe(s)

Now, standard values of \Delta H_f\ of\ all\ participants\ of\ reaction.

\Delta H_f(Al_2O_3)=-1669.8\ KJ/mol\\\Delta H_f(Fe_2O_3)=-822.2\ KJ/mol\\\Delta H_f(Al(s))=0\ KJ/mol\\\Delta H_f(Fe(s))=0\ KJ/mol\\

Now, We know \Delta H_{rxn}=\Delta H_{products}-\Delta H_{reactants}

Putting all values of \Delta H_f to above equation.

We get,

\Delta H_{rxn}=-847.6\ KJ/mol.

Hence, this is the required solution.

Increasing the concentration of a reactant shifts the position of a chemical equilibrium towards formation of more products. wha
Natalija [7]
<h2>The required "option is e)".</h2>

Explanation:

  • The Rate of formation of products depends on the concentration of reactants or the forward reaction increases on increasing the rate of the concentration.
  • There is no effect on the equilibrium rate when the concentration of reactants and products is constant.
  • Forward reaction slows down when the reactant concentration is decreased.
  • On increasing the amount or concentration of reactant the chemical  equilibrium shifts towards formation of more products.
  • Hence, the forward reaction speeds up.
