Im confused. what can be inferred from the graph? a. the reaction reaches equilibrium at 2.75 seconds. b. the amount of reactant is greater than the amount of product at equilibrium. c. the reaction converts all the products back into reactants. d. the amount of reactants and products is equal at 14 seconds. e. the reaction between a and b is product favored.

The correct answer is Option A.

Explanation:

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.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
