Given statement true or not? For the reaction : `2NOCl(g) hArr 2NO(g)+Cl_2(g) , K_p=K_c`.

Explanation

To determine whether the statement "For the reaction: `2NOCl(g) ⇌ 2NO(g) + Cl2(g)`, Kp = Kc" is true or not, we will analyze the relationship between Kp and Kc using the formula and the concept of ΔNg (change in the number of moles of gas).

### Step-by-Step Solution:

1. **Understand the Relationship Between Kp and Kc:**
The relationship between Kp and Kc is given by the equation:
\[ K_p = K_c \cdot R^T \cdot \Delta N_g \]
where:
- \( R \) is the universal gas constant,
- \( T \) is the temperature in Kelvin,
- \( \Delta N_g \) is the change in the number of moles of gas.

2. **Calculate ΔNg:**
ΔNg is calculated as the difference between the total number of moles of gaseous products and the total number of moles of gaseous reactants.
- **Products:** From the reaction \( 2NO(g) + Cl_2(g) \), we have:
- 2 moles of NO
- 1 mole of Cl2
- Total = 2 + 1 = 3 moles of gas (products)
- **Reactants:** From the reaction \( 2NOCl(g) \), we have:
- 2 moles of NOCl
- Total = 2 moles of gas (reactants)
- Now, calculate ΔNg:
\[ \Delta N_g = \text{(moles of products)} - \text{(moles of reactants)} = 3 - 2 = 1 \]

3. **Determine if Kp Equals Kc:**
Now, substitute ΔNg into the relationship:
\[ K_p = K_c \cdot R^T \cdot \Delta N_g \]
Since ΔNg is 1, we have:
\[ K_p = K_c \cdot R^T \cdot 1 = K_c \cdot R^T \]
This means that Kp is not equal to Kc unless R^T is equal to 1, which is not generally the case.

4. **Conclusion:**
Since ΔNg is not zero (it is 1), we conclude that:
\[ K_p \neq K_c \]
Therefore, the statement "Kp = Kc" is **false**.

### Final Answer:
The statement is **false**.
