Answer:
Tripling the concentration of A will triple the reaction rate.
Explanation:
<em>Rate = k[A].</em>
<em>Rate ∝ [A].</em>
<u><em>So, Tripling the concentration of A will triple the reaction rate.</em></u>
The formula of the hydrate = CuSO₄• 3H₂O
Given
4.175 grams sample CuSO₄• xH₂O
3.120 grams anhydrous compound CuSO₄
Required
The formula
Solution
mass of H₂O driven off :
= 4.175 - 3.12
= 1.055 g
MW CuSO₄ = 159.5 g/mol
MW H₂O = 18 g/mol
mol ratio of CuSO₄ : H₂O :
= 3.12/159.5 : 1.055/18
= 0.01956 : 0.05861
= 1 : 3
