The atoms move more rapidly.
C. The approach of the scientific method varies from one scientist to another.
Answer: The starting pressure of is 1.39 atm.
Explanation:
Initial p 0 0
eq'm p-x 0 2x
Total pressure at equilibrium = p - x + 2x = p + x = 1.9...(1)
...(2)
Solving equation (1) and (2). we get x = 0.51
p + x = 1.9
p= 1.9 - 0.51 = 1.39 atm
The starting pressure of is 1.39 atm.
