bonds formed between two ions by the transfer of electrons. The speed at which a chemical reaction proceeds is known as the rate of reaction. The rate of almost every reaction can be increased or decreased due to different factor. Scientists have identified five factors that affect the rate of reaction. The five factors are temperature‚ concentration of the reactants‚ surface area‚ agitation (mixing)‚ and catalyst (chemical helpers). The collision theory states that the rate of a reaction is directly

Due Thursday 28th- 1000 words Social and personal factors in one’s life influence and change our own sense of belonging. Peter Skrzynecki in his suite of poems “Immigrant Chronicle” and J.R.R Tolkien in his 1937 fictional novel “The Hobbit” both explore how social and personal factors influence an understanding of acceptance and belonging in their respective texts.

Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate
