A certain first-order reaction is 27.5 percent complete in 8.90 min at 25°C. What is its rate constant?

jeyben [28]

Answer:

$k= 0.145min^{-1}$

Explanation:

Hello there!

In this case, according to the given information, it turns out necessary for us remember that the first-order kinetics is given by:

$ln(A/A_0)=-kt$

Whereas the 27.5% complete means A/Ao=0.275, and thus, we solve for the rate constant as follows:

$k=\frac{ln(A/A_0)}{-t}$

Then, we plug in the variables to obtain:

$k=\frac{ln(0.275)}{-8.90min}\\\\k= 0.145min^{-1}$

Regards!

Which of the following properly describes the movement of atoms as they represent the states of matter? Atoms making liquids hav

7nadin3 [17]

Answer:

Atoms making liquids have less attraction than solids, but more than gases

Explanation:

The attraction between atoms in different molecules in a solid is very strong due to strong intermolecular forces present in a solid. However, such intermolecular forces are weaker in liquids than in solids.

This implies that the solid has higher intermolecular forces of attraction compared to gases and liquids. Based on the negligible degree of intermolecular forces between them, a gas has the weakest intermolecular forces hence the atom has very minimal interaction between them.

How much time will it take a car traveling at an average of 75 mph to go a distance of 225 miles

mojhsa [17]

Time taken = 3 hours

<h3>Further explanation</h3>

Given

speed : 75 mph

distance : 225 miles

Required

time taken

Solution

An equation of constant velocity motion

$\large {\boxed {\bold {d = v \times \: t}}}$

d = distance = m

v = speed = m / s

t = time = seconds

Input the value :

t = d : v

t = 225 miles : 75 miles/hour

t = 3 hours
