Answer #1

ANSWER;

The formula to find rate of the reaction is

K = Ae

Where K = rate constant

A = frequency factor

e = mathematical quanity

EA = activation energy

R = gas constant (8.31)

T = tempertaure in Kelvin

on sub the value 20 in the equation we will get 1.21 *10 and for 30 it will be 2.23

By increasing the temperature by 10°, the rate of reaction to almost double. This is the value in the rule-of-thumb often used in simple rate of reaction work.The rate constant goes on increasing as the temperature goes up, but the rate of increase falls off quite rapidly at higher temperatures.

The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins and is typically written as k=Ae−Ea/RT where R is the gas constant (8.314 J/mol⋅K), A is a constant called the frequency factor, and Ea is the activation energy for the reaction. However, a more practical form of this equation is lnk2k1=EaR(1T1−1T2) which is mathmatically equivalent to lnk1k2=EaR(1T2−1T1) where k1 and k2 are the rate constants for a single reaction at two different absolute...
