15. A marble chip weighing one gram and once gram of powdered chalk (both CaCO,) were placed in two similar beakers half full of I M HCL. The chalk dissolved in seconds whereas the marble chip was still visible after a few minutes. The most likely ex- planation of this is that A) different reactions were taking place. B) the chalk dissolved quickly because of its degree of purity. C) acids react quickly with all powdered substances, D) the rate of reaction depended on particle size. E) chalk is more soluble in HCI.
