Question

Gaseous carbon monoxide and hydrogen gas can be used to prepare methanol (CH₃OH) . Calculate a value for the reaction quotient when the partial pressures are

P _ { \mathrm { Co } }

= 15.0 atm,

P _ { \mathrm { H } _ { 2 } }

= 15.0 atm,

P _ { \mathrm { CH } _ { 3 } \mathrm { OH } }

= 1.00 atm.

The reaction quotient is calculated using the partial pressures of the reactants and products at a given moment. The expression for the reaction quotient (Q) for the reaction CO(g) + 2H2(g) <=> CH3OH(g) is:Q = P(CH3OH) / [P(CO) * P(H2)^2]Substituting the given partial pressures into the expression, we get:Q = 1.00 atm / [(15.0 atm) * (15.0 atm)^2] = 2.96 * 10^-4Therefore, the reaction quotient is 2.96 * 10^-4.
