Enter your answer in the provided box. Remember to enter your answer to the correct number of significant figures. For the reaction: A(g) + B(g) → AB(g) the rate is 0.25 mol/L·s, when [A]0 = [B]0 = 1.0 mol/L. If the reaction is first order in B and second order in A, what is the rate when [A]0 = 3.1 mol/L and [B]0 = 3.5 mol/L?

8.409 mol/L.s

Explanation:

A(g) + B(g) → AB(g)

It is given that the reaction is first order in B and second order in A

R = k [A]² [B]

where R = rate of the reaction

k = rate constant

[A] = concentration of reactant A at any time

[B] = concentration of reactant B at any time

At the start of the reaction,

rate is 0.25 mol/L·s, when [A]₀ = [B]₀ = 1.0 mol/L

Substituting these into the rate equation, we solve for the rate constant

0.25 = k (1²) (1)

k = 0.25 L²/mol².s

The rate when [A]₀ = 3.1 mol/L and [B]₀ = 3.5 mol/L

R = 0.25 [A]² [B]

R = 0.25 × (3.1)² × (3.5)

R = 8.40875 = 8.409 mol/L.s

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
