Question

Which of the following chemical equations shows a reaction at equilibrium, and what is the reason? 

NO, + co NO • CO2
Because the moles of gas are equal on each side
N2 ) + Oz ) = 2NO
Because the double arrow is present
Option 2
Option 4
2502 () + O2 (0) 2SO3 )
Because it is a balanced equation
N2 ) + 3H2 9) = 2NH, ) + HEAT
Because "HEAT" is part of the reaction
