You start by diving each quantity given by the atomic wight of each element:
Phosphorus (P)
Hydrogen (H)
Then you divide by the lowest number:
for phosphorus
for hydrogen
So the empirical formula will be:

The appropriate scatter plot that depicts the correct division for using Divide center to draw trend line is the plot D.
<h3>What are Scatter plots?</h3>Scatter plots are used to show how much one variable affects another by plotting data points on a horizontal and vertical axis. Each row in the data table is represented by a marker, the position of which is determined by the values of the columns set on the X and Y axes. Scatter plots are graphs that show the relationship of two variables in a data set. It is a two-dimensional plane or a Cartesian system that represents data points.
In order to draw a trend line correctly, divide the points using the divide center method. The dividing vertical line must be drawn at the midpoint (a position where the number of data points to the left and right of the vertical line is equal).
Only option D has a vertical line dividing the 6 data points into two equal portions when the options are evaluated based on this condition.
The diagram is attached.

<u>Answer:</u> The value of for the reaction at 550.3 K is 247.83
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
The chemical equation for the production of methanol follows:
The expression of for above equation follows:
We are given:
Putting values in above equation, we get:
Hence, the value of for the reaction at 550.3 K is 247.83
