If too many Lava Rocks are placed in the rack of a barbeque, what is likely to happen?

Placing too many lava rocks in the rack of a barbecue can lead to the burner burning out prematurely. When there is an excessive amount of lava rock, it can obstruct the flow of heat generated by the burner. Lava rocks are designed to help distribute heat evenly and retain it, but if the volume is too high, insufficient air circulation can occur. This may cause the burner to overheat, leading to failure or burnout due to thermal stress. Proper spacing and the correct amount of lava rocks are essential to ensure effective heat distribution and protect the integrity of the burner, thus preventing premature failure.

The other options do not accurately reflect the implications of overloading lava rocks. An increase in temperature or reduced cooking time would suggest enhanced performance rather than a malfunction, and the barbecue still has the capacity to ignite even with excessive lava rocks, though it may not burn efficiently.
