what is the rate of a first-order reaction that has a reactant concentration of 1.1M and a rate constant of 0.14/s?
rate = k*concn
To calculate the rate of a first-order reaction, you need the reactant concentration and the rate constant. The rate equation for a first-order reaction is given by the formula:
Rate = k * [A]
Where:
- Rate is the rate of the reaction
- k is the rate constant
- [A] is the reactant concentration
In this case, you are given that the reactant concentration [A] is 1.1M and the rate constant k is 0.14/s. Now, you can substitute these values into the rate equation to find the rate:
Rate = 0.14/s * 1.1M
To simplify the calculation, you need to convert the concentration from molarity (M) to moles per liter (mol/L).
1M = 1 mol/L
So, 1.1M = 1.1 mol/L
Now you can calculate the rate:
Rate = 0.14/s * 1.1 mol/L
Multiplying these values together gives:
Rate = 0.154 mol/(s * L)
Therefore, the rate of the first-order reaction with a reactant concentration of 1.1M and a rate constant of 0.14/s is 0.154 mol/(s * L).
