Question

Which of the following is not true: If the K_eq for a particular reaction is less than 1, the products are favored over the reactants. The K_eq is defined as the concentrations of products divided by the concentrations of reactants. An endothermic reaction requires the input of energy. None of the above Heat is evolved in the following reversible reaction: A + B C + D + heat. Based on LeChatelier's principle, applying heat to the reaction would: have no effect on the reaction. Result in the production of more C + D. result in the production of more A + B none of the preceding Which statement best describes the way a catalyst works? It decreases the value of Delta H. It increases the value of Delta H. It decreases the value of E_act. It increases the value of E_act. It increases the value of Delta G. Which of the following conditions characterizes a system in a state of chemical equilibrium? Concentrations of reactants and products are equal Rate of forward reaction has dropped to zero Reactants are being consumed at the same rate they are being produced Reactant molecules no longer react with each other Product concentrations are greater than reactant concentrations A rapid reaction is distinguished by being unaffected by catalysts. having a large heat of reaction. having a small heat of reaction. having a large value of activation energy. having a small value of activation energy. For a chemical reaction to occur, all of the following must happen except chemical bonds in the reactants must break. reactant particles must collide with enough energy for change to occur. reactant particles must collide with the correct orientation. a large enough number of collisions must occur. chemical bonds in the products must form.

Explanation / Answer

1)
if Keq > 1 --> products are favoured
if Keq <1 --> reactants are favoured
endothermic reaction requires energy and exothermic reaction gives energy
Answer: A

2)
applying heat will favour endothermic process which is backward reaction
