In a first–order reaction (a → b and rate = k [a]), tripling the concentration of a will have what effect on the reaction rate?

Tripling the concentration of A will triple the reaction rate.

Explanation:

Rate = k[A].

Rate ∝ [A].

So, Tripling the concentration of A will triple the reaction rate.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
