In which one of the following reactions, the yield of the product will be maximum ?
` 2 A + B hArr C, K = 10^(-5), C + 2 D hArr E, K = 10^(5) , D + 3 B hArr f, K = 10^(3).`

Explanation

To determine in which of the given reactions the yield of the product will be maximum, we need to analyze the equilibrium constants (K) provided for each reaction. The equilibrium constant indicates the extent to which a reaction proceeds to form products; a higher K value suggests a greater yield of products.

### Step-by-Step Solution:

1. **Identify the Reactions and Their K Values:**
- Reaction 1: \( 2A + B \rightleftharpoons C \), \( K = 10^{-5} \)
- Reaction 2: \( C + 2D \rightleftharpoons E \), \( K = 10^{5} \)
- Reaction 3: \( D + 3B \rightleftharpoons F \), \( K = 10^{3} \)
