Solve for t In(A/B) -kt where B-1.65 x 102 M A 1.00 x 10 M. k-4.80 x 104s* and t=
myrzilka [38]

Answer:

t=5.84\times 10^{-5}s

Explanation:

  • First rearrange the whole equation by keeping t in one side and rest parameters in another side of equation
  • Then plug-in all the given values for each parameters and get the solution

ln(\frac{A}{B})=-kt

or, t=\frac{1}{-k}\times ln(\frac{A}{B})

Now plug-in all given values:

t=\frac{1}{-4.80\times 10^{4}s^{-1}}\times ln(\frac{1.00\times 10M}{1.65\times 10^{2}M})

So, t=5.84\times 10^{-5}s

Write the balanced equation for the reaction of hydrogen chloride with sodium hydrogen carbonate to give sodium chloride, carbon
marusya05 [52]
These are the formulas of each compound mentioned:

1) Hydrogen chloride: HCl

2) Sodium hydrogen carbonate: NaHCO3 , this is also known as sodium bicarbonate. The number 3 to the right of O is a subscript.

3) Sodium chloride: NaCl

4) Carbon dioxide: CO2. This is also known as carbon anhydride. The number 2 to the right of O is a subscript.

5) Water: H2O. The number 2 to the right of H is a subscript.

The the chemical equation is:

HCl + NaHCO3 → NaCl + CO2 + H2O

Check the balance

element      left side      right side
H                 1+1 = 2        2
Cl                1                 1
Na               1                 1
C                 1                 1
O                 3                 2+1 = 3

Then, given that the number of each element on the left side is equal to the number of elements in the right side, the equation is balanced.

Consider the following reaction: NO( g) + SO 3( g) ⇌ NO 2( g) + SO 2( g) A reaction mixture initially contains 0.86 atm NO and 0
DIA [1.3K]

Answer:

The equilibrium pressure of NO2 is 0.084 atm

Explanation:

Step 1: Data given

A reaction mixture initially contains 0.86 atm NO and 0.86 atm SO3.

Kp = 0.0118

Step 2: The balanced equation

NO( g) + SO3( g) ⇌ NO2( g) + SO2( g)

Step 3: The initial pressures

p(NO) = 0.86 atm

p(SO3) = 0.86 atm

p(NO2) = 0 atm

p(SO2) = 0 atm

Step 4: The pressure at the equilibrium

For 1 mol NO we need 1 mol SO3 to produce 1 mol NO2 and 1 mol SO2

p(NO) = 0.86 -x atm

p(SO3) = 0.86 -xatm

p(NO2) = x atm

p(SO2) = x atm

Step 5: Define Kp

Kp = ((pNO2)*(pSO2)) / ((pNO)*(pSO3))

Kp = 0.0118 = x²/(0.86 - x)²

X = 0.08427

p(NO) = 0.86 -0.08427 = 0.77573 atm

p(SO3) = 0.86 -0.08427 = 0.77573 atm

p(NO2) = 0.08427 atm

p(SO2) = 0.08427 atm

The equilibrium pressure of NO2 is 0.08427 atm ≈ 0.084 atm
