Dynamic Nature of Equilibrium QuizzMCQ’s For All Chapters – Chemistry Class 11th 1. Equilibrium is best defined asStage where the concentration of reactants is less than that of productsStage where concentration of reactants is equal to that of productsStage where the rate of forward reaction is equal to that of backward reactionStage where the concentration of reactants is more than that of productsYour comments:Question 1 of 102. Which of the folowing characterizes Equilibrium Dynamic natureRequires a closed systemCan be physical or chemicalAll of the aboveYour comments:Question 2 of 103. Equilibrium can be attained inall types of systemclosed systemopen systemisolated systemYour comments:Question 3 of 104. A moles of A reactants react with b moles of B reactants to form c moles of product C. Which of the following is true for rate of reaction Rate= k[A][B]Rate=k[A]a[B]bRate=k[A]a+[B]bRate=k[A]a[B]b/[C]cYour comments:Question 4 of 105. Which one of the following is correct about a reversible chemical reaction at equilibrium all chemical reactions have ceasedthe rates of the forward and reverse reactions are equalthe rate constants of the forward and reverse reactions are equalthe value of the equilibrium constant is 1Your comments:Question 5 of 106. Which are not the conditions of setting of an equilibriumAll reactions should be carried out at STPAll reactions should be carried out at constant temperatureAll reactions should be carried out in open containersGaseous reactions should be carried out in closed containersYour comments:Question 6 of 107. When ice is in equilibrium with water,during equilibriumAmount of ice melting is equal to amount of water freezingThere is no melting and no freezingAmount of ice melting is more than amount of freezingAmount of ice is equal to amount of waterYour comments:Question 7 of 108. Which is not the characteristics of equilibriumRate of forward is equal to the rate of backward reactionThe concentrations of reacting substances remains staticThe pressure, temperature ,enthalpy change of the system is zeroReaction completely cease at equilibriumYour comments:Question 8 of 109. In which of the following reaction can equilibrium be attainedReversible reactionCyclic reactionDecomposition reactionIrreversible reactionYour comments:Question 9 of 1010. Rate of reaction is proportional to product of molar concentration of reactants with each concentration term raised to power its stiochiometric coefficient. This is the law of EquilibriumMass actionConstant proportionReciprocal proportionsYour comments:Question 10 of 10 Loading...
