Key Differences in Form and Meaning

First Conditional (If + present simple, will + base verb)
Used for real, likely possibilities in the future

Second Conditional (If + past simple, would + base verb)
Used for unlikely, imaginary, or hypothetical situations

Choosing Between First and Second Conditional in Negotiations

First Conditional: Used when agreement is close
If you increase the quantity, we'll reduce the price.

Second Conditional: Used in early negotiations
If you increased the quantity, we would consider reducing the price.
