Answer:
Reaction happens in both directions..
Explanation:
This is dynamic equilibrium, where the reactants and products are converted into each other at the same rate. If the system is closed and the temperature is held constant, the chemical reaction will achieve dynamic equilibrium.
Answer:
27.99 dm³
Explanation:
Applying
PV = nRT................ Equation 1
Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.
From the question, we were aksed to find V.
Therefore we make V the subject of the equation
V = nRT/P................ Equation 2
Given: n = 1.31 moles, T = 37°C = 310K, P = 904 mmHg = (904×0.001316) = 1.1897 atm
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
V = (1.31×310×0.082)/(1.1897)
V = 27.99 dm³
Gas particles are in constant motion and are very far apart compared to their size.
