Due Date: April $26($Friday$)$ Individual Assignment $+$ Partner Assignment

$($another old exam question$)$ Sulfur dioxide is reacted with oxygen to form sulfur trioxide. Air is fed in $15\%$ excess. Assume air is a $20/80$ split between oxygen and nitrogen. Answer the following questions:

a$.$ Write a balanced stoichiometric equation for this reaction.

b$.$ Estimate the value for $K$ of this reaction at $298K$ and $5$ bars.

c$.$ Estimate the value for $K$ of this reaction at $1000K$ and $5$ bars.

d$.$ Does raising the pressure to $5$ bars $($relative to $1$ bar$)$ favor an increase in the mole fraction of reactants or products? Explain.

e$.$ Estimate the partial pressure of sulfur dioxide at $0\%$ fractional conversion $(1000K$ and $5$ bar$).$

f$.$ Estimate the partial pressure of sulfur dioxide at $15\%$ fractional conversion $(1000K$ and $5$ bar$).$

g$.$ What is the equilibrium fractional conversion of sulfur dioxide and the partial pressures of all components in the system at equilibrium for the case of $1000K$ and $5$ bars?
