What effect does an increase in products have on the reaction rate of a mixture at equilibrium? A. The forward reaction rate inc
Anna007 [38]

<u>Answer:</u>

<em>D. The reverse reaction rate increases.</em>

<u>Explanation:</u>

The<em> rate of reverse</em> increases if the products are increased in a mixture at equilibrium.

At first,<em> rate of forward and backward</em> reactions are same for a <em>mixture in equilibrium. </em>

<em>If we add products or,the reaction moves to the opposite side I.e towards reactants side.</em>

so,according to the Le Chateliers principle,the reaction shifts opposite to the side of increase. so,according to the Le Chateliers priciple, <em>the rate of reverse or backward reaction will increase with the increase in the products.</em>

Consider the following data for five hypothetical elements: Q, W, X, Y, and Z. Rank the elements from most reactive to least rea
aleksley [76]

Answer:

Y Q W Z X

Explanations:

The most reactive element is the element that will displace an element from it compound . The most reactive element will replace the less reactive element in it compound.

Q+ + Y Reaction occurs

Since the reaction occurs the element Y which is more reactive displaced element Q from it compound.

Q+W+ Reaction occurs

The reaction occurs, that means element Q replaces element w from it compound. Element Q is therefore more reactive than element W.

W+Z+ Reaction occurs

The reaction also occurs . This is an indication that element W replaces element Z in it compound. This means element W is very reactive than element Z.

X+Z+ No reaction

There is no reaction here. This is an indication that element X is less reactive than element Z. This is why element X can't displace element Y in it compound.
