Explain how a catalyst can effect the rate of a forward and reverse reaction.

A catalyst can provide a different mechanism or pathway for a chemical reaction through stabalistion of the transition state. The catalyst will lower the activation energy of the reaction meaning a greater number of molecules will have sufficient energy to react at any one time. A catalyst will increase the rate of both the forward and the reverse reaction.
The activation energy refers to the minimum energy required for a reacting species to undergo a transformation.

Why does the pH of neutral water drop when it is left out in an uncovered container on a worktop for a long period of time?


Q1. Two beakers, A and B, each contain 100.0 cm^3 of 0.0125 mol/dm^3 nitric acid. Calculate the pH of the solution formed after 50.0 cm^3 of distilled water are added to beaker A. Give your answer to 2 decimal places.


How does electrophilic aromatic substitution occur?


0.28 g of a gaseous hydrocarbon was turned in excess oxygen. 0.88 g of carbon dioxide and 0.36 g of water were formed. The volume of 0.28 g of the hydrocarbon at 1.01 x10^5 Pa and 298 k is 123 cm^3. Work out the molecular formula of the hydrocarbon.
