In nature, one common strategy to make thermodynamically unfavorable reactions proceed is to couple them chemically to reactions

padilas [110]

Answer:

$\triangle G= -6.7 KJ/mol$

Explanation:

From the question we are told that:

Chemical Reactions:

X=A⇌B,ΔG= 14.8 kJ/mol

Y=B⇌C,ΔG= -29.7 kJ/mol

Z=C⇌D,ΔG= 8.10 kJ/mol

Since

Hess Law

The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the number of steps taken.

Therefore

Generally the equation for the Reaction is mathematically given by

$T = +1 * X +1 * Y +1 *Z$

Therefore the free energy, ΔG is

$\triangle G=1 * \triangle G*X +1 * \triangle G*Y +1 * \triangle G *Z$

$\triangle G= +1 * (14.9) +1 * (-29.7) +1 * (8.10)$

$\triangle G= -6.7 KJ/mol$

_______ is the amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Kelvin. A. A calorie B. En

Maksim231197 [3]

<h2>The required option d) "specific heat" is correct.</h2>

Explanation:

To raise the temperature of any substance or material of certain mass to respective temperature it requires some amount of heat.
Specific heat is the amount of heat necessary to raise the temperature of the substance of 1 gram to 1 Kelvin.
It is the amount of heat which is required to raise the temperature per unit mass to per unit temperature.
Thus, the required "option d) specific heat" is correct.
