reaction used to determine the experimental rate law of is 2I-(aq) + H2O2(aq) I2(aq) + 2H2O2(l). The rate law determined experimentally is rate= k[I-]1.017[H2O2]0.927. Additionally by performing essentially the same experiments but with temperature changes one can determine how k is affected by temperature changes and the new activation energy. Also‚ from graphs the activation energy was determined to be 33.3 kJ/mol. INTRODUCTION: The rate of a chemical reaction often depends on reactant

(predictor) variables were also studied: when students enrolled‚ number of changes made to their course schedule‚ how many schedule changes were drops and how many were adds‚ and when changes were made. It explores three outcomes: fall semester grade point average‚ fall semester course completion‚ and attrition (whether the students enrolled for the spring semester). Significant relationships were found between several student characteristics and enrollment and registration behaviors. Significant interrelationships

Examine the main trends in the birth and death rates in the UK since 1900 As the population of a country increases‚ there will be certain factors affecting the people of that country; the birth rate‚ and the death rate are two of the major demographic trends. Since 1900 the UK has changed greatly‚ as has the demography of the country. The Birth rate - the number of live births per 1000 of the population per year originally was fairly high due to the fact that child labour was legal in Victorian

Biology Assignment Transpiration rates between Exotic vs. Native plants In this investigation we will be looking at transpiration. The topic we will be focusing on is transpiration rates between native plants as well as exotic plants. We will be experimenting with 2 native plants as well as 2 exotic plants. The reason we are experimenting on this topic is because of Australia’s dry weather‚ we are wanting to find out which plants will be able to hold more water during Australia’s peaking tempretures

AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

Crime in Norfolk Tina Tompkins AIU Online Crime in Norfolk I chose to analyze the crime rate in Norfolk‚ Virginia. I’ll be moving there if my fiancé is re-stationed to the Naval base there. I was curious about how safe it is to live there‚ but it’s not at all. The crime rate is greater than I could have imagined and that makes me uncertain about having to live there. I believe more should be done about it‚ and below is what I think would make it better. In the city of Norfolk there is

Banking Concept: Simplifying RBI Key Policy Rates What are the key policy rates used by RBI to influence interest rates? The key policy or ’signalling’ rates include the bank rate‚ the repo rate‚ the reverse repo rate‚ the cash reserve ratio (CRR) and the statutory liquidity ratio (SLR). RBI increases its key policy rates when there is greater volume of money in the economy. In other words‚ when too much money is chasing the same or lesser quantity of goods and services. Conversely‚ when there
