The heat of the reaction has been -22 kJ/mol. The negative sign has been the indication of the exothermic reaction.

The heat of reaction has been given as the amount of energy absorbed or released by the system to form the products.

The heat of reaction has been given by:

$\Delta H=\Delta H_{reactant}-\Delta H_{product}$

Heat of reaction

The heat of reaction has been calculated based on the bond energies. The energy constituent by each bond in the reactant has been the heat of the reactant, and the energy of product has been the heat of product.

The heat of reactant has been given as:

The reactant molecules have been $\rm CH_3OH$ and $\rm C\equiv O$ .

The bond energy of the reactant has been:

$\Delta H_{reactant}=3\;\times \;\text {C-H}\;+\;\text{C-O + O-H}+\;\text C\equiv \text O\\
\Delta H_{reactant}=3\;\times \;413\;+\;358+467+1070\;\text{kJ/mol}\\
\Delta H_{reactant}=3134\;\text{kJ/mol}$

The heat of reactant has been 3134 kJ/mol.

The heat of product has been given as:

The product molecule has been $\rm CH_3COOH$

The bond energy of the product has been:

$\Delta H_{product}=3\;\times \;\text {C-H}\;+\;\text{C-O + O-H +\;C-C}+\;\text C=\text O\\\Delta H_{reactant}=3\;\times \;413\;+\;358+467+\;347\;+\;745\;\text{kJ/mol}\\\Delta H_{reactant}=3156\;\text{kJ/mol}$

The heat of product has been 3156 kJ/mol.

The heat of reaction has been given as:

$\Delta H=\Delta H_{reactant}-\Delta H_{product}\\
\Delta H=3134-3156\;\text{kJ/mol}\\
\Delta H=-22\;\rm kJ/mol$

The heat of the reaction has been -22 kJ/mol. The negative sign has been the indication of the exothermic reaction.

Answer from: Lalu3677

This is an exothermic reaction.

Explanation:

You can calculate the reaction using the calculation below:

ΔH reac= 3(413Kj/mol) +358Kj/mol +467 Kj/mol +1070 kj/mol = 3134 kj/mol

ΔH prod = 3(413 kj/mol) + 347 kj/mol + 358kj/mol +467kj/mol +745 kj/mol = 3156kj/mol

ΔH = 3134 kj/mol - 3156kj/mol = -22 Kj/mol

Negative results indicate an exothermic reaction.

An image of the reaction is attached below.

Answer from: Quest

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh $pcl_{3}$ +δh $cl_{2}$ ] - [δh $pcl_{5}$ ]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
