Consider the following reaction: 2 NOCl(g) ⇆ 2 NO(g) + Cl2(g) at T = 450. K ΔH°rxn = + 75. kJ/mol A system initially contains NOCl, NO, and Cl2, and is at equilibrium. For each of the following changes, indicate (by circling your answer) whether the number of moles of Cl2 in the system will increase, stay the same, or decrease. a) Add 0.100 moles of NOCl(g) to the system moles of Cl2 will increase, moles of Cl2 will not change or moles of Cl2 will decrease b) Decrease the volume by 1.00 L moles of Cl2 will increase, moles of CL2 will not change, moles of Cl2 will decrease. c) Increase the temperature to T = 500. K moles of Cl2 will increase, moles of Cl2 will not change, moles of Cl2 will decrease.
Consider the following reaction:
2 NOCl(g) ⇆ 2 NO(g) + Cl2(g) at T = 450. K ΔH°rxn = + 75. kJ/mol
A system initially contains NOCl, NO, and Cl2, and is at equilibrium. For each of the following changes,
indicate (by circling your answer) whether the number of moles of Cl2 in the system will increase, stay the
same, or decrease.
a) Add 0.100 moles of NOCl(g) to the system
moles of Cl2 will increase, moles of Cl2 will not change or moles of Cl2 will decrease
b) Decrease the volume by 1.00 L
moles of Cl2 will increase, moles of CL2 will not change, moles of Cl2 will decrease.
c) Increase the temperature to T = 500. K
moles of Cl2 will increase, moles of Cl2 will not change, moles of Cl2 will decrease.
