The enthalpy of formation of water is -285.8 kj/mol. what can be inferred from this statement?

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

Avariable that is not being directly tested during an experiment should be changed varied experimented controlled
