Dungeon room rewards question

are the additional rewards for this iteration of dungeons specific and static to certain room? For instance is dungeon 7 room 13 worth 18,000 t2a catalyst fragments or is it worth a random 500-18000?
If not, do the higher rooms have better drop rates if the higher tiered rewards? @Kabam Miike
