A quantity of 0.0250 mol of a gas initially at 0.050 L and 19.0°C undergoes a constant-temperature expansion against a constant
KiRa [710]

Answer:

V_2=2.995L\\\\W=248.5J

Explanation:

Hello,

In this case, for us to compute the final volume we apply the Boyle's law that analyzes the pressure-volume temperature as an inversely proportional relationship:

P_1V_1=P_2V_2

So we solve for V_2 by firstly computing the initial pressure:

P_1=\frac{nRT}{V_1}=\frac{0.025mol*0.082\frac{atm*L}{mol*K}*(19+273.15)K}{0.050L}  =11.98atm

V_2=\frac{P_1V_1}{P_2}=\frac{11.98atm*0.050L}{0.200atm}\\ \\V_2=2.995L

Finally, we can compute the work by using the following formula:

W=nRTln(\frac{V_2}{V_1} )=0.025mol*8.314\frac{J}{mol*K}*(19.0+273.15)K*ln(\frac{2.995L}{0.050L}) \\\\W=248.5J

Best regards.

The graph shows a student's data from an investigation about plant growth in five plants of the same type. Which is the best way
Daniel [21]
The best way to display this data for analysis would be a line graph because line graphs are used to track changes over short periods of time. when smaller changes exist. Line graphs can also be used to compare changes over the same period of time for more than one group.

What is the relationship between chemical reactions and product
sveticcg [70]
During a chemical reaction, the stuff that reacts together are the reactants. The stuff that is made during the reaction are the products. A catalyst is something that can be added to the reaction that allows it to react faster, but does not get used up during the reaction.
