Solution
The reaction represented by 2K + I2 → 2KI is a synthesis reaction. In a synthesis reaction, two or more simple substances combine to form a more complex substance. In this case, potassium (K) and iodine (I2) are combining to form potassium iodide (KI). So, the correct answer is B. A synthesis reaction.
