Consider the exothermic reaction 4hcl(g) + o2(g)  ⇋  2cl2(g) + 2h2o(g). which of the following should cause the equilibrium to shift right to form more cl2 gas?

I believe the choices in this question are:

A. Lowering the temperature of the reaction. 
B. Lowering the enthalpy of the reaction. 
C. Decreasing the volume of the system. 
D. Adding oxygen gas. 
E. Decreasing the pressure of the system. 

From the choices above, A, B, and D will result in creation of more Cl2 gas.

i think its 5049.

i hope this !
