QUESTIONS 6.67 poir Equilibrium is reached in chemical reactions when o a the concentrations of reactants and products become equal O b the temperature shows a sharp rise. e the rates ofthe forward and reverse reactions become equal o d all chemical reactions stop o e the forward reaction stops QUESTION 10 6.67 poir Which of the following reactions would shift to the right to favor the product side upon increasing the pressure (through a reduction in the volume of the reaction vessel)? Show Timer III, 6 Co2()+6H2o() CoH1206 (s)-602) O I only Question Co b II only c III only e d I and I1I O e II and III QUESTION 11 6.67 poin Ar 800 K the equilabrism costant. kp for the following reaction is 32 10-7 2 H2S(g)= 2 H2(g) * S2(g) A reaction vessel at $00 K initially contains 3.00 atm of H2S. If the reaction is allowed to equilibrate. what is the equilibenum pressure of S2? b14 102 atm 62 10-3

Explanation / Answer

9)

At equilibrium, concentration of reactant and product can be anything depending on the value of equilibrium constant.

But the rate of forward and backward reaction is always equal at equilibrium

Answer: c

10)

Increasing pressure shifts reaction to decreasing gaseous molecule side

So, to shift to right, product should have less molecule

This is true for II
