The rate of a chemical reaction is defined as the change in the concentration of a reactant or a product over the change in time, and concentration is in moles per liter, or molar, and time is in seconds. So we express the rate of a chemical reaction in molar per second.

Answer:

Hey!

Your answer is The Rate of a Reaction is a measurement of how the speed at which a reactant is used up / or a product is formed.

Explanation:

R of R (Rate of Reaction) can be affected by:

Reactant concentration (how much of the substance is there to react)

The state of the reactants (whether they are in a solid/liquid/gas state)

The total surface area (more particles of the substance means more reactions...)

The Temperature (hot=quicker cool=slower)

The presence of a catalyst (catalysts speed up the Rate of the Reaction)

HOPE THIS HELPS!!

Which of the following equations demonstrates an actual chemical reaction that forms a new substance? A.ZN + 2HCl → 2NCl2 + H2 B
alukav5142 [94]

Answer:

A

Explanation:

The first option is the only option where new products are formed.

In the D option no new product is formed.

Same goes with option C.

In B no new products are formed.

Change is said to be taken place only with formation of new products from reactants.

Answer: When using 645 L /s  of O2 in a temperature and pressure of  195°C,  0.88 atm  respectively, we will get 0.355Kg /s NO

Explanation:

  • First we review the equation that represents the oxidation process of the NH3 to NO.

4NH3(g) + 5O2(g) ⟶4 NO(g) +6 H2O(l)  

  • Second we gather the information what we are going to use in our calculations.

O2 Volume Rate = 645 L /s

Pressure = 0.88 atm

Temperature = 195°C + 273 = 468K

NO molecular weight = 30.01 g/mol  

  • Third, in order to calculate the amount of  NO moles produced by 645L/ s of O2, we must find out, how many moles (n) are 645L O2 by using the general gas equation PV =n RT

Let´s keep in mind that using this equation our constant R is 0.08205Lxatm/Kxmol

PV =n RT

n= PV / RT

n= [ 0.88atm x 645L/s] / [ (0.08205 Lxatm/Kxmol) x 468K]

n= 14.781 moles /s of O2

  • Fourth, now by knowing the amount of moles of O2, we can use the equation to calculate how many moles of NO will be produced and then with the molecular weight, we will finally know the total mass per second .

14.781 moles /s of O2 x 4moles NO / 5 moles O2 x  30.01g NO / 1 mol NO x 1Kg NO /1000g NO = 0.355Kg /s NO
