Sabine's reverberation time equation and large spaces

[peter mcc]

I study architecture and i have an acoustics exam next week. I'm stuck on this question.

Why, on its own, can Sabine's famous reverberation time equation not be the complete design basis for large spaces? give two reasons.

any help would be appreciated.
thanks!
