I believe this pertains to chemical reaction? So my guess would be answer A “Fire burning”
Don’t quote me though lol.
I have attached the answer here. hope this helps!
let me know if you have any question
Answer: M = 22/ (i x28.948)
Explanation:
Pi = osmotic pressure = 22atm
T = Temperature = 353K
M = Molarity = ?
R = gas constant = 0.082atm.L/mol/K
i = van’t Hoff factor
Pi = iMRT
M= Pi /(iRT) = 22 / ( i x 0.082 x 353)
M = 22/ (i x28.948)
