Zinc reacts with excess hydrochloric acid to produce zinc chloride and hydrogen gas. what happens to the reaction rate if you increase the concentration of zinc?

a. the reaction rate decreases because the area available for particle movement is decreased.
b. the reaction rate decreases because the probability the reverse reaction is more likely.
c. the reaction rate increases because the energy of each particle increases.
d. the reaction rate increases because the probability of collisions increases.

D.The reaction rate increases because the probability of collisions increases.

Explanation:

We are given that Zinc reacts with excess hydrochloric  acids to produce zinc chloride and hydrogen gas

Now , we have to find the effect on the rate of reaction when the concentration of zinc increases.

When the concentration of zinc increases then the number of moles per unit volume of reactant increases to form product.Therefore, the number of moles per unit volume  of product also increases.

If the concentration of reactant increases then the rate of reaction increases because then large number moles per unit volume  of reactant increases to form the large number of moles per unit volume of product.

When the rate of reaction increases because the probability of collisions of atoms of reactant increases.

Hence. option D is true.

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

that tool would be a compass
