The energy diagram for the reaction X + Y =Z is shown above. The addition of a catalyst to this reaction would cause a change in which of the indicated differences?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

How many moles of gas are present if p=11 atm, v=12l, t=185k?
