Answer:

Explanation:
Hello.
In this case, given the described reaction, the formation of nitric acid turns out:

Since two hydrogen atoms are present at the reactants we balance it as follows:

In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:

Answer:
Faster

increases
Explanation:
The rate of reaction refers to how fast or slow a reaction occurs. The rate of reaction is dependent on factors such as surface area, concentration, temperature, nature of reactants, catalyst etc.
The concentration refers to the amount of reactants present. When the acid is made more concentrated, its amount is increased. This increases the number of collisions between the acid particles and the marble chips ultimately leading to increase in the rate of reaction according to Arrhenius theory.
