State true or false. It is possible to achieve a conversion greater than the equilibrium conversion.

True False

State true or false. A reversible reaction is the one in which the reaction proceeds simultaneously in both directions.

True False

For the reaction A ↔ R, which of the following is the correct expression of CR?

CR = CA0XA CR = CA0XA CR = CR0 + CA0 CR = CR0 + CA0XA

Equilibrium is a state in which ___

Rate of forward reaction > Rate of backward reaction Rate of forward reaction = Rate of backward reaction Rate of forward reaction < Rate of backward reaction Rate of forward reaction is independent of the rate of backward reaction

For the reaction A ↔ R, k1 being the rate constant of forward reaction, k2 being the rate constant of backward reaction and XAe is the equilibrium conversion, k2 is obtained as _____

k2 = k1$$\frac{(1 – X_{Ae})}{(\frac{C_{A0}}{C_{R0}} + X_{Ae})}$$ k2 = k1$$\frac{(1 + X_{Ae})}{(\frac{C_{A0}}{C_{R0}} + X_{Ae})}$$ k2 = k1$$\frac{(1 – X_{Ae})}{(\frac{C_{A0}}{C_{R0}} – X_{Ae})}$$ k2 = k1$$\frac{(1 – X_{Ae})}{(\frac{C_{A0}}{C_{R0}} – X_{Ae})}$$

Which of the following represents second order bimolecular type reversible reaction?

A+B ↔ R+S A ↔ B A ↔ R+S A+B ↔ R

Exponential Linear Logarithmic Quadratic

Which of the following is not a reversible reaction?

Ammonia formation from its elements Formation of hydrogen bromide from its elements Decomposition reaction of nitrogen pentoxide Oxidation of sulphur dioxide to sulphur trioxide

The Le- Chatlier principle states that ____

No reaction is reversible All reactions are reversible at high temperatures A system experiencing disturbance shifts direction of equilibrium to nullify the change A system experiencing disturbance does not shift direction of equilibrium to nullify the change
