Why do rates of reaction change with ph?

PH is also a factor in the stability of enzymes. As with activity, for each enzyme there is also a region of pH optimal stability. In addition to temperature and pH there are other factors, such as ionic strength, which can affect the enzymatic reaction. Hope I helped! :)

Hno3(aq) → h+(aq) + no3−(aq). picture ii best represents the strong acid hno3. strong acids are strong electrolytes
