Learn English – How to express a certain 60-minute period

No, I never heard anyone say that ever. How many times have I heard "how much ever"? Never. Never ever have I heard "how much ever". Some singers say "whatever".

"How much do you prepare?" sounds more natural to me. Additionally, it is not all that matters. The idiom also isn't all that matters yet it is "all that matters", and my source for this one is Metallica song "Nothing Else Matters".

I ran Google Books searches for "a catalyst" plus each of six prepositions: for, in, of, on, to, and with over the period 1900–2005. The resulting Ngram chart shows that, until about 1970, authors had very mixed preferences about which preposition to use:

Over the years 1970–2005, however, "a catalyst for" (blue line) has emerged as the predominant wording, with "a catalyst to" (red line) a modest second, "a catalyst in" (yellow line) a solid third, "a catalyst of" (green line) a steady fourth, and "a catalyst on" (teal line) a relative rarity.

A typical example of "a catalyst for" appears in André-Noël Chaker, Good Governance in Sport: A European Survey (2005):

In new democracies, for instance, the presence of a sports law and an interventionist model may be a catalyst for growth and development of the sports movement.

In contrast, the vast majority of Google Books instances of "a catalyst to" use the phrase to introduce a verb (as in "a catalyst to promote the combustion process") rather than a noun (as in "a catalyst to the Industrial Revolution"). Still, such instances do occur, as in John Schofield & A.G. Vince, Medieval Towns: The Archaeology of British Towns in Their European Setting (2003):

Away from the established centres, expansion took two clear forms: the foundation of new towns, and the spread of market rights and fairs which might be a catalyst to the transformation of loosely formed places into towns.

Though I didn't do an exhaustive study of the search results, "a catalyst of" seems somewhat more common than "a catalyst to" in the setting that the OP asks about. From Boon Kheng Cheah, Malaysia: The Making of a Nation (2002):

Not much recognition has been accorded the communist insurgents for their important role as a catalyst of this development [British decolonization].

Even "a catalyst in" is sometimes used in the relevant sense. From Natalie La Balme, "Constraint, Catalyst, or Political Tool," in Decisionmaking in a Glass House (2000):

Some observers feel that public opinion can also act as a catalyst in the decisionmaking process.

Even "a catalyst on" is not unknown in such situations, although instances are few. From Gerritt Voogt, Constraint on Trial: Dirck Volckertsz Coornhert and Religious Freedom (2000):

At the same time, the Renaissance acted as a catalyst on the intellectual development in parts of Europe, especially urbanized regions such as the Italian city-states and the Low Countries.

All of these formulations involve descriptions of things that act as catalysts with regard to a process or development, which is essentially the sense that the OP asks about. In such contexts, using any of the five prepositions discussed here might be defensible. But in writing, at any rate, "a catalyst for" has become by far the most common choice in recent decades.
