Question

Identify the options below that are examples of concentrations of reactants affecting the rate of a reaction (select all that apply) a. Calcium reacts at a moderate rate with water to form hydrogen and a base, whereas sodium reacts in a similar way in mere seconds.

b. A 5 M sample of hydrogen peroxide decomposes at a faster rate than a 2 M sample of the same volume. c. Calcium carbonate deteriorates more rapidly in polluted air than in clean air. d. Finely ground table salt reacts with sulfur dioxide more quickly than small chunks of salt in a grinder.
