which one was the fastest to react‚ I hypothesized that the reaction would occur the fastest with the 3% hydrogen peroxide (the highest amount of concentration) because the higher the concentration the more faster the reaction occurs and helps produce or break up the enzyme. After testing all three of my substrate concentrations with 10 trials each‚ my data showed (first graph) that the 3% substrate concentration had the fastest average rate at 0.19 of distance and time occurring and my second data

Premium Chemical equilibrium Rate equation Reaction rate
chemical components are not conserved. If reactions occur on a system‚ the number of moles of an individual component will increase if it is a product and will decrease if it is a reactant. The unit of CCE is moles of component per unit time. While EE‚ the first law of thermodynamics puts forward the principle of conservation of energy. The unit of EE is energy per time. General balance equation: Input+ generation- output-consumption= accumulation Rate law ra-1 = rb-1 = rc11 =r1r1= k1CA rc2-1=

CHM1051 Chemistry CHM1051 has been designed for students who have demonstrated a strong aptitude for chemistry during secondary studies‚ eg. a VCE Chemistry Study Score >=37. On completion of this unit‚ students will have gained an understanding of how atoms and molecules interact with each other and how this affects their bonding‚ reactivity‚ 3D structure and physical properties. A number of important topics such as stoichiometry‚ intermolecular forces‚ thermodynamics‚ kinetics‚ equilibria‚

velocities the scale growth rate is enhanced by an increase in fluid velocity due to the mass transfer-controlled scale growth. At higher fluid velocities‚ the scale growth rate decreases with increasing fluid velocity due to the increased flow erosion effect‚ for slurry systems. This suggests the potential of particulate erosion as a scale suppression mechanism. The model predicts the existence of an optimal slurry flow velocity‚ where scaling rate and equipment erosion rate are both zero. The optimal

Enzymes are biological molecules‚ or proteins‚ that act as catalysts. Enzymes help complex reactions so that they may occur everywhere in life. For example‚ when you eat meat‚ the proteases work to help break down the peptide bonds that occur among the amino acids. Enzymes usually work to complete one specific job which makes them specific catalysts. They also won’t be found all over the body‚ enzymes are found in neural cells‚ intestinal cells‚ and saliva. Enzymes are among the many organic macromolecules

I knew that the more water in the glass would make the Alka-Seltzer dissolve slower but the warmer temperature would speed it up a little bit. 4. What was your prediction about the results of each factor tested in your two lab procedures? Explain your predictions based on your knowledge of the dissolving process‚ collision theory‚ and reaction rates. My prediction was right and I knew this experiment was perfect
