x

Step-by-step explanation:

because if you are dong it 0 times it would be just x (make sense?)

This is an incomplete question, here is the complete question.

The solid XY decomposes into gaseous X and Y:

Kp = 4.1 (at 0°C)

If the reaction is carried out in a 22.4 L container, which initial amounts of X and Y will result in the formation of solid XY?

a) 2.0 mol X; 2.0 mol Y

b) 6 mol X; 0.6 mol Y

c) 1 mol X; 1 mol Y

d) None of the above

Answer : The correct option is, (D) None of the above

Explanation :

Reaction quotient (Q) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

The given balanced chemical reaction is,

The expression for reaction quotient will be :

Q = [X] [Y]

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.

The given equilibrium constant value is,

Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.

If the initial amount of X and Y to form XY then the product of their product must be greater than Kp.

Now we have to calculate the product of partial pressure.

PV = nRT

Moles of X      Moles of Y      Pressure of X     Pressure of Y       Q

2.0                    2.0                  2.00                   2.00                4.00

6                       0.6                 6.00                    0.6                  3.6

1                         1                     1.00                    1.00                 1.00

There are 3 conditions:

When that means product > reactant. So, the reaction is reactant favored.

When that means reactant > product. So, the reaction is product favored.

When that means product = reactant. So, the reaction is in equilibrium.

From the above we conclude that, in all the three options that means product < reactant. So, the reaction is product favored that means reaction must shift to the product (right) to be in equilibrium. That means the reaction will not move to the left to form XY.

Hence, the correct option is, (D)

I'm going to assume that "âˆ’" is supposed to be some kind of minus character, so that the given system of DEs is supposed to be

Take the Laplace transform of both sides of both equations. Recall the transform for a second-order derivative,

where F(s) denotes the transform of f(t). You end up with

and solving for X(s) and Y(s) (nothing tricky here, just two linear equations) gives

Now solve for x(t) and y(t) by computing the inverse transforms. To start, split up both X(s) and Y(s) into partial fractions.

• Solving for x(t) :

Taking the inverse transform, you get

• Solving for y(t) :

Inverse transform:

Please attach the graphs! Thanks! :)

(11) Ans: limit doesn't exist (Option C)
Given function:

If both sides are equal on applying limit then limit does exist.

Let check:
If x<-1: answer would be -1+1 = 0
If x≥-1: answer would be 1-(-1) =2

Since both are not equal, as 0≠2, hence limit doesn't exist (Option C).

(12) Ans: Option (B) 7.

Given function:

If all of above three are equal upon applying limit, then limit exists.

When x < 0 -> 7-(0)^2 = 7
When x = 0 -> 7
When x > 0 -> -10(0) + 7 = 7

ALL of the THREE must be equal. As they are equal. Hence the correct option is (B) 7.
