At 10C zinc reacts with 2.0M sulphuric acid to produce 17 mL hydrogen gas in 20 s
a) what is the rate of this reaction?
b)What volume of hydrogen might be produced in 20 s at 30C?
To find the rate of a reaction, we need to consider the change in the amount of a reactant or product over time. In this case, we know that the reaction between zinc (Zn) and sulfuric acid (H2SO4) produces hydrogen gas (H2).
a) To find the rate of this reaction, we can calculate the amount of hydrogen gas produced per unit time. Given that 17 mL of hydrogen gas is produced in 20 seconds, we divide the volume of hydrogen gas by the time:
Rate = (volume of hydrogen gas) / (time) = 17 mL / 20 s = 0.85 mL/s
Therefore, the rate of this reaction is 0.85 mL/s.
b) To determine the volume of hydrogen gas that might be produced in 20 seconds at 30°C, we need to consider two factors: the temperature and the reaction rate.
The reaction rate generally increases with temperature, following a principle known as the Arrhenius equation. However, to accurately determine the new reaction rate, we would need additional information or experimental data.
Since we don't have specific information about the rate at 30°C, we can't directly calculate the volume of hydrogen gas produced. We could estimate the change in the rate by assuming an increase in reaction rate due to the elevated temperature. But without more information, any estimate would be speculative.
In conclusion, without additional data or knowledge about the reaction rate at 30°C, we cannot determine the exact volume of hydrogen gas that might be produced in 20 seconds at that temperature.
