yanalaym [24]

Answer:

ΔG° is for ideal (fixed) or standard conditions which cannot be found at the cellular level while ΔG is dependent on the quantities of reactants and products present at a specific time

Explanation:

ΔG° is fixed value for a given reaction that indicates the direction in which the reaction will proceed in a chemical equation under ideal conditions and because conditions within a cell varies and are unlike standard conditions, ΔG° cannot predict the direction of a cellular reaction at any given time. To predict the direction of progression of a reaction within the cell, ΔG is used, which depends on the amounts of the reactants and products present at a particular time

When menthol, CH3OH, is burned in the presence of oxygen gas, O2, a large amount of heat energy is released. For this reason, it

Drupady [299]

We have the following balanced equation:

$CH_3OH_{(g)}+\frac{3}{2}O_{2\text{ (g)}}\rightarrow CO_{2\text{ (g)}}+2H_2O_{(l)}$

They also give us the heat of reaction equal to -764 kJ, i.e. it is an exothermic reaction.

By observing the reaction, we can deduce that for this heat to be generated, one mole of methanol is needed. Now let's see how many grams that mole of methanol equals. We will use the molecular weight equal to 32.04 g/mol

$\begin{gathered} g\text{ of methanol = 1 mol }\times\text{ 32.04 g/mol} \\ g\text{ of methanol }=\text{ 32.04 g} \end{gathered}$

Now we know the grams of methanol that generate 764 kJ, because the heat of reaction is directly proportional to the mass of the reactants, we can apply a rule of three to know the grams needed to produce a heat of reaction equal to 701 kJ:

$\begin{gathered} \frac{32.04\text{ g of methanol}}{764\text{ kJ}}=\text{ }\frac{x\text{ g of methanol}}{701\text{ kJ}} \\ x\text{ g of methanol = }\frac{32.04\text{ g of methanol }\times\text{ 701 kJ}}{764\text{ kJ}} \\ g\text{ of methanol = 29.4 g} \end{gathered}$

So, 29.4 g of methanol must be found to produce 701 kJ of heat
