6.79 x 10⁶

<h3>Further explanation </h3>

Scientific Notation consists of 2 parts

1. the first part: the first digit followed by the decimal point

2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point

To add/subtract, the exponents must be the same and then add/subtract the coefficient

convert the largest exponent

$\tt 7.2\times 10^6\rightarrow 72\times 10^5$

subtract the coefficients

$\tt =(72-4.1)\times 10^5\\\\=67.9\times 10^5\rightarrow 6.79\times 10^6$

Calculate the rate constant, k k , for a reaction at 60.0 60.0 °C that has an activation energy of 80.1 80.1 kJ/mol and a freque

Answer:

0.24 s-1

Explanation:

We first list the parameters as shown in the image attached. The variables are now properly substituted. This equation is used to calculate the rate constant and clearly show us the dependence of the rate constant on temperature. From this equation, we can clearly and easily see that the rate constant increases exponentially with increase in temperature of the reaction system.
