The correct response I believe is D. The reaction rate increases because the probability of collisions increases as there are more Zn atoms to react.
Yes it is polluting the river with everything the manufaturing plant gives off such as the chemicals released in the air
The activity series goes top to bottom, most active to least active elements, going: Li, K, Ba, Sr, Ca, Na, Mg, Mn, Zn, Fe, Cd, Co, Ni, Sn, Pb, H, Cu, Ag, Hg, Au.
Thus, your list of metals would go from most reactive to least reactive: Li, K, Mg, Zn, Fe, Cu, Au
