SI unit for pressure is Pascal
Answer:
the correct choice would be: 4. Reaction rates are not related to spontaneity.
Explanation:
The speed of reaction is independent of spontaneity, since it depends on other factors such as the amount of reagent.
The amount of reagent is one of the variables that most influences the speed of reaction, the greater the amount of reagent, the faster the reaction will be and thus the speed will be increased.
Atoms are the smallest particles of an element that can take part in a chemical reaction. During any chemical reaction no particles are created or destroyed: the atoms are simply rearranged from the reactants to the products. The products may have different properties to the reactants.
Mass is never lost or gained in chemical reactions. We say that mass is always conserved. In other words, the total mass of products at the end of the reaction is equal to the total mass of the reactants at the beginning.
This fact allows you to work out the mass of one substance in a reaction if the masses of the other substances are known.
Answer: The rate law is ![rate=k[CH_3COOC_2H_5]^1[NaOH]^1](https://tex.z-dn.net/?f=rate%3Dk%5BCH_3COOC_2H_5%5D%5E1%5BNaOH%5D%5E1)
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
For the given reaction:

k= rate constant
Rate law: ![rate=k[CH_3COOC_2H_5]^x[NaOH]^y](https://tex.z-dn.net/?f=rate%3Dk%5BCH_3COOC_2H_5%5D%5Ex%5BNaOH%5D%5Ey)
For the given rate law:
y =1 = order with respect to 
n = total order = 2
2= (x+y)
2= (x+1)
x= 1
Thus order with respect to
is 1 and rate law is : ![rate=k[CH_3COOC_2H_5]^1[NaOH]^1](https://tex.z-dn.net/?f=rate%3Dk%5BCH_3COOC_2H_5%5D%5E1%5BNaOH%5D%5E1)
