Question
Consider the equilibrium: A B. Which statement is not true? At equilibrium: [A] and [B] reach steady state values. the rates of forward and reverse reactions are equal the concentrations of A and B are equal the equilibrium constant is equal to [B]/[A] both (a) and (b) are not true Consider the equilibrium: A B. K is measured as 342 at 25 deg C. A reaction is run and it is found that [A] = 0.0010 M and [B] = 0.10 M Which statement is true? the reaction is at equilibrium the reaction must shift left to attain equilibrium the reaction must shift right to attain equilibrium it is impossible for the reaction to attain equilibrium K = 1 Consider the equilibrium: A B. K is measured as 0.25 at 25 deg C. A reaction is run and it is found that [A] = 0.010 M and [B] = 5.00 M Which statement is true? the reaction is at equilibrium the reaction must shift left to attain equilibrium the reaction must shift right to attain equilibrium it is impossible for the reaction toExplanation / Answer
Solutions.
1.Answer is e. That is both (a) & (b ) are not true. But at equilibrium these two are true.
2.Answer is b. That is the reaction must to shift to left to attain equilibrium. Because the concentration of B is more than A.
3.Answer is b.That is the reaction must shift to left to attain equilibrium. Because the concentration of B is more than A,due to this reaction shift to backward and attain equilibrium state.
