Consider the chemical equation C(s) + 2A(g) S 2B(1) + heat. Be suré to JUSTIFY each answer below. (a) Will SQUEEZING the container cause a disturbance to equilibrium? If so, then in what direction will the reaction occur? (b) Will RAISING THE TEMPERATURE of the system cause a disturbance to equilibrium? If so, then in what direction will the reaction occur? (c) What is the sign of the standard reaction ENTHALPY? Does the enthalpy change provide a favorable or unfavorable contribution to the spontaneity of the forward reaction at standard state conditions?

Transcribed Image Text:7.B Consider the chemical equation C(s) + 2A(g) 5 2B(I) + heat. Be sure to briefly
JUSTIFY each answer below.
(a) Will SQUEEZING the container cause a disturbance to equilibrium? If so, then
in what direction will the reaction occur?
(b) Will RAISING THE TEMPERATURE of the system cause a disturbance to
equilibrium? If so, then in what direction will the reaction occur?
(c) What is the sign of the standard reaction ENTHALPY? Does the enthalpy change
provide a favorable or unfavorable contribution to the spontaneity of the
forward reaction at standard state conditions?
(d) What is the sign of the standard reaction ENTROPY? Does the entropy change
provide a favorable or unfavorable contribution to the spontaneity of the
forward reaction at standard state conditions?
(e) Based on (c,d) describe the preference for products or reactants at equilibrium
at very LOW temperatures.
(f) Based on (c,d) describe the preference for products or reactants at equilibrium
at very HIGH temperatures.
