Plot the activity coefficients of Na+, Ca2+, andAl3+ for ionic strengths from 0.001M (very fresh water) to 0.5M (seawater). Determine the ionic strength and TDS at which the activity coefficient corrections become important (activity coefficient less than 0.95) for monovalent, divalent, and trivalent ions.

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.
