which of the following choice fits in the blank to complete the equation

Answers

Answer 1

To complete the equation, the blank should be filled with "ΔH°- ".

Option B is correct.

How do we explain?

The equation represents the standard Gibbs free energy change (ΔG°) in a chemical reaction in terms of the enthalpy change (ΔH°) and the entropy change (ΔS°). The equation is:

ΔG° = ΔH° - TΔS°

ΔG° represents the change in Gibbs free energy,

ΔH° represents the change in enthalpy,

T represents the temperature in Kelvin, and ΔS° represents the change in entropy.

The minus sign indicates that the change in Gibbs free energy is determined by the difference between the enthalpy and the product of temperature and entropy.

The heat capacity for the metals are;

Aluminum - 0.89

Copper - 0.11

Iron - 0.44

Lead - 0.12

What is the specific heat?

The specific heat of a substance is denoted by the symbol "C" and is typically measured in units of J/g·°C (joules per gram per degree Celsius) or cal/g·°C (calories per gram per degree Celsius).

The specific h

We have that;

For Aluminum;

c = 4.184 * 39.85 * 4.7/11.98 * 72.9

= 783.6/873.3

= 0.89

For Copper;

c = 4.184 * 12.14 * 1.9/12.14 * 75.4

= 96.5/915.3

= 0.11

For Iron

c = 4.184 * 40.24 * 2.4/12.31 * 75.1

= 404.1/924.5

= 0.44

For Lead

c = 4.184 * 39.65 * 0.7/12.46 * 76.7

c = 116.1/955.68

= 0.12

What is the free energy?

Free energy takes into account both the enthalpy (heat content) and entropy (degree of disorder) of a system. It provides a measure of the system's ability to do useful work or drive chemical reactions.

The formula for calculating free energy is:

G = H - TS

where:

G is the Gibbs free energy

H is the enthalpy (heat content) of the system

T is the temperature in Kelvin

S is the entropy (degree of disorder) of the system
