Project 1 Hypothesis Construction

The hypothesis should be; "Increasing the amount of ice increases the rate at which the ice will melt"

<h3>What is a hypothesis?</h3>

The term hypothesis refers to a tentative explanation that could be applied in order to explain an observation. When we give a hypothesis, it must be subjected to rigorous experimentation thus it can be confirmed or repelled by experiment.

Now, we can see that the question here is; "How does the amount of salt added to ice affect the rate at which the ice will melt?" This implies that the correct hypothesis here ought to have to do with the impact of the amount of ice in the affirmative.

Thus, the hypothesis should be; "Increasing the amount of ice increases the rate at which the ice will melt"

The reactant concentration in a first-order reaction was 7.60 x 10-2 M after 35.0 s and 5.50 x 10-3 M after 85.0 s. What is the
8090 [49]

Answer:

k = -0.0525 s⁻¹

Explanation:

The equaiton for a first order reaction is stated below:

ln[A]=−kt+ln[A]₀.

[A] = 5.50 x 10⁻³ M

[A]₀ = 7.60 x 10⁻² M

t = 85.0 - 35.0 = 50.0 s

The rate constant is represented by k and can be calculated substituting the values given above:

k = (ln[A]₀ - ln[A])/t

k = (ln5.50 x 10⁻³ M - ln7.60 x 10⁻² M)/50.0s

k = -0.0525 s⁻¹
