Final answer:

The window air conditioner with a coefficient of performance of 3 and consuming 2 kW of electricity would provide 6 kW of cooling or heating when operational.

Explanation:

The window air conditioner in the question consumes 2 kW of electricity and has a coefficient of performance (COP) of 3. The COP refers to the ratio of the cooling or heating provided by an air conditioner to the total electrical input, revealing its efficiency. In this case, to calculate the cooling or heating the air conditioner would provide, you would simply multiply the COP by the power consumption. Hence, the rate of cooling or heating the air conditioner would provide is 3 (COP) * 2 kW = 6 kW.
