concentration of a species can affect reaction rate in the determination of rate law and rate constant. 2. To determine how temperature affects reaction rate. Introduction Chemical kinetics deals with the speed‚ or rate‚ of a reaction and the mechanism by which the reaction occurs. We can think of the rate as the number of events per unit time. The rate at which you drive (your speed) is the number of miles you drive in an hour (mi/hr). For a chemical reaction the rate is the number of moles that

The Iodine Clock Investigation Introduction This is an investigation into the rate of a reaction and the factors that contribute to how fast a reaction will take place. Through the recording and analysis of raw data‚ this investigation also allows us to apply generally accepted scientific rules and to test them against results gained from accurate experimental procedures. Aim The aim of this experiment is to investigate the rate at which iodine is formed when the concentration

Bags of Reactions * Problem/Purpose * Background Information: The Law of Conservation of Mass was created by Antoine Lavoisier in the 18th century. This law stated that mass could matter could neither be created nor destroyed. During a reaction the bonds of the reactants are broken and form new substances. As stated in the Law of Conservation‚ matter can neither be created nor destroyed; because of this the products should have the same number and type of atoms as seen in the reactants

When one thinks of anthropology‚ the mind tends to skip to a foreign land with exotic people and customs‚ yet we often forget to pay attentions to the different cultures that are close to home. Throughout the past few decades‚ technology has had an increasing impact on our culture. The development in technology is driven by those who have a passion for delving deep into the underlying mechanics to unravel mysteries of the technology and to further develop it for both their own needs and the needs

It is almost a month when we had our educational tour for our subject‚ History 23‚ which toured us in historical places of Batangas and Laguna. Packed with excitement to learn and to see ancestral things‚ I prepared my things up even before the exact date of our tour. It was on the first day of August 2012‚ Wednesday at 6:00 in the morning‚ when our journey which I called “time travel” begun. Our first itinerary was on the ancestral house of Dr. Jose Rizal in Calamba‚ Laguna‚ where our national

Today’s laws are not as harsh as Hammurabi’s. They are more civilized. For example‚ none of today’s laws include amputating other people’s body parts. Hammurabi thought it was necessary to amputate arms‚ breasts‚ digits‚ etc. I believe our laws are better‚ overall because they do not incorporate corporal punishment. I think Hammurabi’s Code of Law was an excellent deterrent against crime‚ and very few people would try to break the law. I think this is due to how harsh the laws were. There was zero
