10.3 g of will produce from 12.7 g
.
In simple terms, a limiting reagent is a reactant that is completely used up in the reaction.
It is also referred to as a limiting reactant or limiting agent.
Now, according to the question,
Since it is a limiting reagent, it will react fully.
The mass of that will be produced will be:-
Equivalent mole of = Equivalent weight of
= 12.7/169.97 = x*2/274x = 10.3 g.
Hence, 10.3 g of will be produced.
It is used to restrict the reaction.
It tells you the estimated amount of compound to be used.
It brings quantitative understanding to chemical reactions.

Answer:
True.
Explanation:
- Catalyst increases the rate of the reaction without affecting the equilibrium position.
- Catalyst increases the rate via lowering the activation energy of the reaction.
- This can occur via passing the reaction in alternative pathway (changing the mechanism).
- The activation energy is the difference in potential energies between the reactants and transition state (for the forward reaction) and it is the difference in potential energies between the products and transition state (for the reverse reaction).
- in the presence of a catalyst, the activation energy is lowered by lowering the energy of the transition state, which is the rate-determining step, catalysts reduce the required energy of activation to allow a reaction to proceed and, in the case of a reversible reaction, reach equilibrium more rapidly.
- with adding a catalyst, both the forward and reverse reaction rates will speed up equally, which allowing the system to reach equilibrium faster.
