Consider the following reaction. SO2Cl2 → SO2 + Cl2. After collecting experimental data you found that plotting ln[SO2Cl2] vs. t

Nikitich [7]

Answer:

$[SO_2Cl_2]_{600}= 0.0842 M$

Explanation:

Some theoretical knowledge is required here. We should understand that whenever we plot the natural logarithm, ln, of a concentration vs. time and obtain a straight line, this indicates a first-order reaction. That said, since this is the case here, we have a first-order reaction with respect to $SO_2Cl_2$ .

The linear equation has the following terms:

$y = -0.000290t - 2.30$

It is a linear form of the integrated first-order law equation:

$ln[SO_2Cl_2]_t = -kt + ln[SO_2Cl_2]_o$

Therefore, the rate constant, k, is:

$k = 0.000290 s^{-1}$

The natural logarithm of initial molarity is:

$ln[SO_2Cl_2]_o = -2.30$

Using the equation, we may substitute for t = 600 s and obtain the natural logarithm of the concentration at that time:

$ln[SO_2Cl_2]_{600} = -0.000290 s^{-1}\cdot 600 s - 2.30 = -2.474$

Take the antilog of both sides to find the actual molarity:

$[SO_2Cl_2]_{600}=e^{-2.474} = 0.0842 M$

Sally and Sue took a canoe trip down the Mississippi River. Their average speed for the trip south was 20 miles/hour. 20 miles/h

Anna35 [415]

Speed is the time rate at which Sue covers the distance. It is derived by dividing the total distance covered by the total time taken to cover the distance . Usually SI unit for speed is km/h or mph or m/s.

Explanation:

Speed is also referred to as velocity- so the two are synonymous.

Acceleration is the rate at which speed is increasing. It is usually given by SI unit m/s². The opposite of acceleration is deceleration which is the rate at which speed is decreasing.

Distance is the measurement, in meters of kilometers or miles or yards..etc, that has been covered from one point to another.
