The equilibrium expression shows the ratio between
products and reactants. This expression is equal to the concentration of the
products raised to its coefficient divided by the concentration of the
reactants raised to its coefficient. The correct equilibrium expression for the
given reaction is:<span>
I think line b would be more viscous because it took a longer time to flow through the tube. Viscous means the resistance of fluids an example would be that molasses has a higher viscosity than water.
