50 points consider the following equation in chemical equilibrium. c2h4(g) + h2(g) mc009-1.jpg c2h6(g) + 137 kj what happens to the amount of ethane (c2h6) when the temperature of the system is increased? the amount of ethane decreases. the amount of ethane increases initially and then decreases. the amount of ethane increases. the amount of ethane decreases initially and then increases.

The correct answer is the amount of ethane decrease. Because this reaction is an exothermic reaction and the heat is a product  of the reaction, So when the number of temperature increases, so (More heat will be added) So the reaction will go leftward (towards reactants) So the amount of c2h4 & H2 Will increase and the amount of ethane C2H6 will decrease. Hope this helps you!:)

Given:

The equation of the ellipse is

The length of its major axis is 6.

To find:

The value of k.

Solution:

The standard form of an ellipse is

Where, a>b and 3a is the length of major axis.

We have,

Divide both sides by k.

Here, .

So, the length of the major axis is

Therefore, the value of k is 18.
