Consider the following equation:

[tex]\( A(g) + B(g) \rightarrow C(g) \)[/tex]

As the concentration of [tex]\( A(g) \)[/tex] increases, the frequency of collisions of [tex]\( A(g) \)[/tex] with [tex]\( B(g) \)[/tex]

A. decreases
B. remains the same
C. increases


Sagot :

Let's analyze the given chemical equation:
[tex]\[ A(g)+B(g) \rightarrow C(g) \][/tex]

### Step-by-step Solution:

1. Understanding the Reaction:
- This is a chemical reaction where two gases [tex]\( A(g) \)[/tex] and [tex]\( B(g) \)[/tex] react to form a product [tex]\( C(g) \)[/tex].

2. Effect of Concentration on Collision Frequency:
- In the context of gases, the rate at which reactions occur depends largely on the frequency of collisions between the reacting molecules.
- According to collision theory, for a reaction to occur, the reactant molecules must collide with sufficient energy and proper orientation.

3. Increasing Concentration:
- If the concentration of [tex]\( A(g) \)[/tex] is increased, this means there are more molecules of [tex]\( A(g) \)[/tex] present in a given volume.

4. Impact on Collision Frequency:
- With more molecules of [tex]\( A(g) \)[/tex] present, the likelihood of [tex]\( A(g) \)[/tex] molecules colliding with [tex]\( B(g) \)[/tex] molecules increases.
- Hence, the frequency of collisions between [tex]\( A(g) \)[/tex] and [tex]\( B(g) \)[/tex] will increase.

Therefore, based on the above analysis, the correct answer is:

(2) increases.
