5 . Reaction Speed Equation:Indicate three sources of error that might affect the experimental results ....

Name three possible sources of error in a calorimetry experiment.

In this problem, we have to list four factors or variables that can affect the date of reaction so. Pretty. Mhm. Following four factors. Mhm. Yeah. Can affect the rate of reaction. Excuse me. Mhm. Yeah. Mhm. Are really stood below. Yeah. First factories concentration. Yeah. Mhm. Mhm. The second factor is temperature. Mhm. Yes. What third factories catalyst and fourth factories. Mhm. Surface area of the accidents. As we increase the concentration of reactant, the rate of chemical reaction increases. Generally a catalyst increases the rate of reaction. The rate of chemical reaction usually increases with the increase in temperature. And if a reactant or catalyst is solid, the rate of reaction increases with the increase in surface area. Because greater the surface area finally divided, cutest are more effective. Mhm. Yeah.

Mhm. For this question, it describes you making five measurements of the rate of a reaction. For each measurement, you determine the rate constant. The values of four of the rate constants are very close to each other within experimental error. When it suggests that there within experimental error, they're referring to errors associated with the random nature of data collection. Where due to random errors, we get some values high in some values low. The other, however, is quite different. The 5th value, the question is, is your result likely to represent a different rate or an error in calculation? It is highly likely that it is an error in calculation or an error in data collection is very common to have one outlier that comes from what is called a blunder or a mistake in data collection. Or in your calculation, the first thing I would do is go back and review your calculations.

So five factors that can affect the rate of the action is the presence of or of absence of a catalyst, the second area, the nature of the reactive, the pressure and finally, our temperature.

Hello. So they were going to be talking about what influences the rate of a reaction. So here we have some expressions. This is a first water rate expression, second order rate expression, and so on and so forth. And so we can see that the rates dependence on the very constant and the concentration off the reactive. So one factor is just the concentration of the reactive. It's more racked. Ins means faster eat. But what about this K value with this K depend on Well, we see that. But get K is going by the Arrhenius equation here. So as we look at this equation will notice. Well, okay, depends on temperature, so temperature influences the rate we also have activation. Energy also also influences the rate and remember that Ah, catalyst can lower the activation energy and thus increase the rate. So the the presence of a catalyst is also a factor. Then this A Here is the collision frequency, which can change of fewer if you're running a reaction in a different situation, like versus in the air versus on organic solvent. So collision frequency is also a factor. And for, say, if you have a solid reactant. Um, if you have a solid reactant and it has a greater surface area versus if it has a smaller surface area, ah, larger surface area will cause the reaction to go at a faster rate because the concentration of the reacting because that is greater. So another possible ah factor is for solids, for solid, reactant is and catalysts a larger surface area. So there we go. I would say that our main factors are the concentrations of the reactant temperature, uh, activation energy and probably the presence of the catalysts. So they're ago. He looked at some situations that would change.
