The reaction reaches equilibrium at 2.75 seconds
pav-90 [236]3 years ago
3 0

<u>Answer:</u> The correct answer is Option A.

<u>Explanation:</u>

Equilibrium is defined as the condition when the concentration of the reactants and products are constant. The ratio of their concentration remains constant, it does not vary.

The forward reaction and backward reaction occur at the same rate.

Rate of forward reaction = Rate of backward reaction

From the graph, it is clearly visible that the reaction reached equilibrium a 2.75 seconds, where the concentration of reactants and concentration of products are constant. After this point, the concentration of products starts to increase and the concentration of reactants starts to decrease.

Hence, the correct answer is Option A.

An unknown compound is processed using elemental analysis and found to contain 117.4g of platinum 28.91 carbon and 33.71g nitrog
dlinn [17]

Answer:

1 mole of platinum

Explanation:

To obtain the number of mole(s) of platinum present, we need to determine the empirical formula for the compound.

The empirical formula for the compound can be obtained as follow:

Platinum (Pt) = 117.4 g

Carbon (C) = 28.91 g

Nitrogen (N) = 33.71 g

Divide by their molar mass

Pt = 117.4 / 195 = 0.602

C = 28.91 / 12 = 2.409

N = 33.71 / 14 = 2.408

Divide by the smallest

Pt = 0.602 / 0.602 = 1

C = 2.409 / 0.602 = 4

N = 2.408 / 0.602 = 4

The empirical formula for the compound is PtC₄N₄ => Pt(CN)₄

From the formula of the compound (i.e Pt(CN)₄), we can see clearly that the compound contains 1 mole of platinum.

How are viscosity and flow rate similar
Stels [109]

Answer: Flow rate is inversely proportional to viscosity.

Explanation: The relation is called Poiseuille's law, which describes the smooth flow of a fluid along a tube.
