What is the rate of effusion of methane, ch₄, relative to the rate of effusion of acetylene, c₂h₂?

1.274.

Explanation:

∨ ∝ 1/√M.

where, ∨ is the rate of diffusion of the gas.

M is the molar mass of the gas.

∨₁/∨₂ = √(M₂/M₁)

∨₁ is the rate of effusion of the methane.

∨₂ is the rate of effusion of acetylene gas.

M₁ is the molar mass of methane (M₁ = 16.0 g/mol).

M₂ is the molar mass of acetylene (M₂ = 26.0 g/mol).

∴ The rate of effusion of methane, CH₄, relative to the rate of effusion of acetylene, C₂H₂ = ∨₁/∨₂ = √(M₂/M₁) = √(26.0 g/mol)/(16.0 g/mol) = 1.274.

b.

the accuracy of the data.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
