One important relationship between chemical and mechanical weathering is

mechanical weathering can produce smaller pieces of rock that have more surface area for chemical weathering to work on.

Explanation:

As mechanical weathering breakdown the rocks into smaller pieces, mechanically, the chemical weathering on the rocks also increases. This is because smaller pieces of the rock have a larger surface area to volume ration on which chemical weathering can act upon. This even further increases the weathering of the rock.
