Investigating The Factors Which Affect The Rate of Reaction Between Limestone and Acid Rain(Hydrochloric Acid)
Background knowledge
Rainwater is always slightly acidic, as carbon dioxide in the air dissolves in rain to form carbonic acid. Acid rain is rain, snow or fog that is polluted by acid in the atmosphere and damages the environment. Two common air pollutants acidify rain: sulphur dioxide (SO2) and nitrogen oxide (NOX). When these substances are released into the atmosphere, they can be carried over long distances by prevailing winds before returning to earth as …showed first 75 words of 5449 total…

…showed last 75 words of 5449 total…rate of reaction of the graphs between 100 and 150 seconds. To find this I needed to work out the gradients of the 1M, 1.25M, 1.5M, 1.75M, 2M lines, between 100 and 150 seconds.
1M = 14.5/20 = 0.29 rate of reaction
1.25M = 19/20 = 0.38
1.5M = 26/50 = 0.52
1.75M = 31/50 = 0.62
2M = 36.5/50 = 0.73
Concentration (M)<Tab/>Rate of Reaction at 100-150 seconds
1<Tab/>0.29
1.25<Tab/>0.38
1.5<Tab/>0.52
1.75<Tab/>0.62
2<Tab/>0.73
