KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.

![**Gibbs Free Energy Calculation for a Chemical Reaction**
**Objective:**
Calculate the Gibbs free energy (in kJ) at 25 degrees Celsius for the following chemical reaction using the data provided in the table.
**Chemical Reaction:**
\[ 1A + 1B + 4C \rightarrow 4D + 3E \]
**Data Table:**
| Species | \(\Delta H_f^0\) (kJ/mol) | \(S^0\) (J/mol·K) |
|---------|----------------|--------------|
| A | -82.84 | 121.97 |
| B | 91.68 | 170.11 |
| C | -89.37 | 12.15 |
| D | -88.02 | 41.54 |
| E | 64.03 | 32.33 |
**Explanation:**
- \(\Delta H_f^0\) represents the standard enthalpy of formation for each species.
- \(S^0\) denotes the standard entropy for each species.
- The given values are used to calculate the Gibbs free energy change (\(\Delta G\)) using the equation:
\[
\Delta G = \Delta H - T\Delta S
\]
Where:
- \(\Delta H = \Sigma (\Delta H_f^0 \, \text{products}) - \Sigma (\Delta H_f^0 \, \text{reactants})\)
- \(\Delta S = \Sigma (S^0 \, \text{products}) - \Sigma (S^0 \, \text{reactants})\)
- \(T\) is the temperature in Kelvin (25°C = 298 K).
**Instructions:**
1. Calculate \(\Delta H\) using the given enthalpies of formation.
2. Calculate \(\Delta S\) using the given entropies.
3. Use the Gibbs free energy equation to find \(\Delta G\).
This calculation will indicate the spontaneity of the reaction under standard conditions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7a00ba11-4727-4380-bbb0-88ea42161338%2Fd32ebb52-1b83-4d27-bd05-aaa79ebda0af%2Fe7ado7.jpeg&w=3840&q=75)
