Answer:
0.0018 mol/min is the average rate of carbon dioxide gas production in moles per minute during the 10 minutes.
Explanation:
Pressure of carbon dioxide gas = P = 0.25 atm
Volume of carbon dioxide gas = V = 5.0 L
Moles of carbon dioxide gas = n
Temperature of the carbon dioxide gas,T = 550°C = 550+273 K = 823 K
Using an ideal gas equation :


n = 0.018 mol
In 10 minutes pressure of carbon dioxide gas reached to 0.25 atm
Average rate of production of moles of carbon dioxide gas per minute in duration of 10 minutes:

0.0018 mol/min is the average rate of carbon dioxide gas production in moles per minute during the 10 minutes.

1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.
