What is the name for this piece of lab equipment?scalesnewton metermass balancespring balanceQuestion 9 of 10 Loading... 10. Why a catalyst does not affect the position of equilibrium in a reversible reaction?If a reversible reaction is in dynamic equilibrium, a catalyst increases the rate of the forward reaction and the rate of the backward reaction by the same amount, so the position of equilibrium is unaffectedA catalyst reduces the activation energy, and is not used upA reaction in dynamic equilibrium already has the lowest possible activation energyA catalyst has no effect on a forward or backward reactions if it is in dynamic equilibriumQuestion 10 of 10 Loading...
