Which outcome occurs when hydrogen gas accumulation exceeds LEL?

💡 Explanation

If hydrogen concentration exceeds the lower explosive limit (LEL), ignition triggers rapid flame propagation because a chain-branching explosion MECHANISM dominates, resulting in an exponential increase in burning velocity. Therefore, rapid burning occurs, rather than catalytic enhancement or changes in material properties which are separate.
