A student is measuring the effect that surface area has on the rate of chemical weathering. He dissolves several 5-gram samples of calcite in acid. The samples range from a single rock, to several small pieces, to a fine powder. He observes that the 5 grams of powder dissolve the fastest, and the single 5-gram rock dissolves the slowest. Based on this information, how might mechanical weathering affect the rate of chemical weathering?
