Match the items of column I to those of column I:
`{:(Column-I, Column-II),((A)"Cell constant",(p) E_("cathode")^(0)+E_("anode")^(0)),((B)Anode,(q)l//A),((C)"Conductance",(r)"Mass of product by 1 coulomb of electricity"),((D)"Electrochemical equivalent",(s)("Resistance")^(-1)),((E)E_(cell)^(0),(u)"Involve oxidation"):} `

Answer

To solve the matching question, we will analyze each item in Column I and find its corresponding item in Column II based on the definitions and relationships in electrochemistry.

### Step-by-Step Solution:

1. **Cell Constant (A)**:
- The cell constant is defined as the ratio of the length of the electrode to the area of the electrode. It is represented as \( \text{Cell Constant} = \frac{l}{A} \).
- Therefore, the correct match for Cell Constant is **(q) \( l//A \)**.

2. **Anode (B)**:
- The anode is the electrode where oxidation occurs in an electrochemical cell.
- Thus, the correct match for Anode is **(u) "Involve oxidation"**.

3. **Conductance (C)**:
- Conductance (G) is the reciprocal of resistance (R). Therefore, it can be expressed as \( G = \frac{1}{R} \).
- Hence, the correct match for Conductance is **(s) \( (\text{Resistance})^{-1} \)**.

4. **Electrochemical Equivalent (D)**:
- The electrochemical equivalent refers to the mass of a substance produced or consumed at an electrode during electrolysis per unit charge (1 coulomb).
- Therefore, the correct match for Electrochemical Equivalent is **(r) "Mass of product by 1 coulomb of electricity"**.

5. **E_cell^0 (E)**:
- The standard cell potential \( E_{cell}^0 \) is calculated as the sum of the standard reduction potential at the cathode and the standard oxidation potential at the anode.
- Thus, the correct match for E_cell^0 is **(p) \( E_{cathode}^0 + E_{anode}^0 \)**.

### Final Matching:

- (A) Cell constant → (q) \( l//A \)
- (B) Anode → (u) "Involve oxidation"
- (C) Conductance → (s) \( (\text{Resistance})^{-1} \)
- (D) Electrochemical equivalent → (r) "Mass of product by 1 coulomb of electricity"
- (E) \( E_{cell}^0 \) → (p) \( E_{cathode}^0 + E_{anode}^0 \)
