Question
6. Consider the following reaction at equilibrium 2CO2(g) 2CO(g) + O2(g) + heat The addition of O2 to this reaction container will a decrease the amount of Co2(8) at equilibrium. b.) increase the value of the equilibrium constant. c.) increase the amount of CO2 (g) at equilibrium. d.) increase the amount of CO(g) at equilibrium. e.) decrease the value of the equilibrium constant. 7. Refer to the reaction in question 6. An increase in temperature ill a.,) increase the concentration of colg). b.) increase the concentration of CO2(g) decrease the concentration of CO2(g). d.) increase the value of the equlibrium constant. e.) increase the concentration of O2(g). 8. The effect of a catalyst on an equilibrium is to a.) slow the reverse reaction only b.) shift the equilibrium to the right c.) increase the equilibrium constant so that the products are favored. d.) increase the rate of the forward reaction only. e increase the rate at which equilibrium is achieved without changing the composition of the equilibrium mixture.Explanation / Answer
2CO2(g) <---------------> 2CO(g) + O2(g) + Heat
2CO2(g) <---------------> 2CO(g) + O2(g) DH = -ve The forward reaction is exothermic reaction
6.
Increase the conc of products the equilibrium shift to left side.So conc of reactants are increases.
C. increase the amount of Co2(g) at equilibrium.
7.2CO2(g) <---------------> 2CO(g) + O2(g) DH = -ve The forward reaction is exothermic reaction
The forward reaction is exothermic reaction. The exothermic reaction takes place at low temperature.
The tempereture increases back ward reaction endothermic reaction takes place.
b. increase the concentration of CO2(g)
8.e.
At equilibrium catalyst increase the rate of forward reaction and rate of reverse reaction
