Potential energy diagrams represent the energy transfer in chemical reactions in a diagram called a potential energy graph and/or a reaction progress curve. A potential energy diagram shows the adjustment in potential energy of a system as reactants are changed.

What is the total number of liters of SO3 produced when 32.0 of SO2 reacts completely

ahrayia [7]

Write the chemical equation for reaction
that is
2SO2+O2 --->2SO2

find the moles of SO2 used = moles=mass/molar mass of so2

= 32g/80g/mol=0.4 moles

by use of reacting ratio between SO2 and SO3 which is 2:2 therefore the moles of so3 is also = 0.4 moles

STP 1 mole = 22.4L.
what about 0.4moles

= 0.4 /1 x22.4=8.96 liters

Draw a chair conformation for cis-1-bromo-2,4-dimethylcyclohexane showing equatorial and axial positions at the carbon atoms bea

Ahat [919]

Answer:

See attachment.

Explanation:

Mono-substituted cyclohexanes are more stable with their substituents in an equatorial position. However, with poly-substituted cyclohexanes, the situation is more complex since the steric effects of all substituents have to be taken into account. In this case, you can see that <u>the interconversion is shifted towards the conformation in the bottom because there is less tension between the substituents</u>.

The reactant concentration in a second-order reaction was 0.560 m after 115 s and 3.30×10−2 m after 735 s . what is the rate con

Aloiza [94]

Use the formula for second order reaction:

$\frac{1}{C} = \frac{1}{C_0} + kt$

C = concentration at time t
C0 = initial conc.
k = rate constant
t = time

1st equation : $\frac{1}{0.56} = \frac{1}{C_0} + 115k$

2nd Equation: $\frac{1}{0.033} = \frac{1}{C_0} + 735k$

Find $\frac{1}{C_0}$ from 1st equation and put it in 2nd equation:

$\frac{1}{0.033} = \frac{1}{0.56} - 115k + 735k$

$\frac{1}{0.033} - \frac{1}{0.56} = 620k$

k = 0.046
