Based on pressure values for each component of the reaction, what is the value of the reaction quotient, Q?
Equation: C2H2 + 2 H2 -> C2H6
C2H2 has a pressure of 5.05 atm
H2 has a pressure of 4.35 atm
C2H6 has a pressure of 0.0225 atm
Reaction quotient is defined as
Q = p(C2H6)/p(C2H2)*p(H2)^2
where p(C2H6) means the partial pressure of C2H6, p(C2H2) means partial pressure of C2H2) etc.
Now just plug in the values listed and calculate Q.
To find the value of the reaction quotient, Q, we first need to determine the partial pressure of each component in the reaction. The reaction quotient compares the concentrations (or in this case, partial pressures) of the reactants and products at a given point in the reaction.
In this equation: C2H2 + 2 H2 -> C2H6, the reaction involves C2H2 and H2 as reactants, and C2H6 as the product.
Given that C2H2 has a pressure of 5.05 atm, H2 has a pressure of 4.35 atm, and C2H6 has a pressure of 0.0225 atm, we can use these values to calculate the value of Q.
The reaction quotient, Q, is calculated by taking the product of the partial pressures of the products, divided by the product of the partial pressures of the reactants, each raised to the power of their respective stoichiometric coefficients.
Q = (P[C2H6]) / (P[C2H2] * P[H2]^2)
Substituting the given pressure values:
Q = (0.0225 atm) / (5.05 atm * (4.35 atm)^2)
Simplifying:
Q = 0.0225 / (5.05 * 4.35^2)
Now you can use a calculator to find the numerical value of Q using these equations.
