This is a Multiple part question. Please write step by step that way I can study from this problem. Thank you.

(a).

Complete the following equilibrium table.

2HI_(g) ⇌ H_2(g) + I_2(g)

Initial 0.1600 M 0 0

Change

─────────────────────────────

Equilibrium

(b). Determine equilibrium values for [HI] and [H₂] if [I₂] = 0.0227 M at equilibrium.

(c). Write the expression (with substances in brackets) for K_C.

(d). Substitute equilibrium concentrations in the expression, and determine the value for K_C.

(e). Write the expression (with substances in brackets) for Q_C.Include the “i” subscripts.

What does the “i” stand for? Describe the difference between Q_C and Kc.

Expert Solution

2HI_(g) ⇌ H_2(g) + I_2(g)

I 0.16 0 0

C -2*0.0227 0.0227 0.0227

E 0.16-2*0.0227 0.0227 0.0227

0.1146

Kc = [H2][I2]/[HI]²

= 0.0227*0.0227/(0.114)² = 0.039

Kc>Qc the equilibrium shift ot right side.

This is a two part solution. Please include step by step solution that way I can study from this. Thank you. Equation (24.2): 3I^-(aq) + H2O2(aq) + 2H3O^+(aq) ---> I3^-(aq) + 4H2O(l) Equation (24.11): 2 S2O3^2-(aq) + I3^-(aq) ---> 3 I^-(aq) + S4O6^2-(aq) Part 1: Add equations 24.2 and 24.11 together.What happens to I-1 and I3-1? What should happen to their concentrations while S2O3-2 is present? Inspect equations 24.2 and 24.11 again. What will happen to the concentration of I3-1...

Can I please get a step by step (either video or written out) for this question. I don't know where to find the step by step videos. They are EXTREMELY helpful. The inverse demand for a homogeneous-product Stackelberg duopoly is P = 16,000 -4Q. The cost structures for the leader and the follower, respectively, are CL(QL) = 3,000QL and CF (QF) = 6,000QF.. a. What is the follower’s reaction function? b. Determine the equilibrium output level for both the leader...

I need a step by step way to solve this, not just an answer please. THX On Jan 1, 2017 Sharpsburg, Inc. issued $400,000, ten-year, 10% bonds for $354,200. The bonds pay interest on June 30 and December 31. The market rate is 12%. What is the carrying value of the bonds at the end of the ten years. According to the book the answer should be $400k, NOT $355,452 like another Clegg member answered.
