The answer is a. True. This is also known as the Le Chatelier's principle or The Equilibrium Law which states that if a chemical reaction is at equilibrium and then experiences changes in the condition of the reaction such as changes in concentration, pressure, or temperature of products or reactants, the system will naturally shift to achieve a new equilibrium state.
I think it would be true, hope this helped. Have a great day! :D
...acid rain can eat away metals, it’ll corrode them, but to affect the rate?? I’m pretty sure some elements can neutralize acid, perhaps slow down its reaction, like limestone for example. A lake lined with limestone will neutralize any acid fallen into the water. But as for a statue, I’m not sure but it must be something similar... sorry I can’t be more of a help :\
