How acetic acid is converted into acetamide ?

What is the equilibrium constant of aa+bb=cc+dd

*will mark you brainliest + 15 points ** why does the equilibrium of a system shift when the pressure is increased? a. to maximize the stress on the system b. to stop restoring equilibrium to the system c. to increase the total moles of gas in the system d. to decrease the total moles of gas in the system

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
