Question

Iodine fluoride gas (IF) decomposes to gaseous iodide (I₂) and fluoride (F₂) at a high temperature. If K_p at this high temperature is 19.7, determine the equilibrium partial pressure of IF gas if its initial concentration was 0.306 atm? Hint: You should write a balanced chemical equation for the reaction described.

Question 6 options:

	0.153 atm
	0.0689 atm
	0.168 atm
	0.0310 atm
	0.138 atm

Answer 1

Given reaction - 21F, I2 (9) +72-19). latto t-teq -0.306 -0.306-28 2 Hece, pressloce is given instead of miles given Kp = 1907 for this reaction- We know- kp = P2 PEZ 417) 19-7 x-x 40-306–22) 19-7/42=1-2242 = 2² +0.093636) 77-84-24-1128x+1.8446292=0 2 Solving this quadratic equation by x= za -b I b²yac we get x= 0.17 242379 this is not possible, x = 0-1375093 because for this 0-306-22 will be negative so_equilibou um poortial pressure = 0.306-22 = 0.0309814 Ang (2) p = 0.0310 atm
