Question

What is the reaction quotient, Q, for the chemical reaction below at 298K with [A] = 0.5 M, [B] = 2.0 M, and [C] = 1.0 M?2A + 3B ⇌ 4C

Answer 1

The reaction quotient, Q, is calculated using the concentrations of the reactants and products raised to the power of their stoichiometric coefficients. For the given reaction:2A + 3B  4CThe formula for Q is:Q =  [C]^4  /  [A]^2 * [B]^3 Given the concentrations [A] = 0.5 M, [B] = 2.0 M, and [C] = 1.0 M, we can plug these values into the formula:Q =  1.0^4  /  0.5^2 * 2.0^3 Q =  1  /  0.25 * 8 Q = 1 / 2Q = 0.5So, the reaction quotient, Q, for the given reaction at 298K with the provided concentrations is 0.5.
