Question

According to the temperature of quotient equation decreasing the temperature of 10 degree the rate of reaction becomes
a.1/2
b.2/3
c.1
d.2

Answer 1

When temperature of the reaction medium is decreased by 10°C , the rate of reaction becomes ½.

• This value is obtained from various experimental procedures.

• It is usually observed that when the temperature of the reaction medium is increased by 10°C , the rate of reaction changes by a factor of 2.

• It is also referred to as the Q_(10) temperature coefficient

• It is defined as the change in biochemical rates when the system temperature changes by 10° C.

$\boxed{ \sf{Q_{10} = { \bigg( \dfrac{R_{2}}{R_{1}} \bigg )}^{ \frac{10}{ T2 - T1} } }}$

• "R" stands for rate of reaction , "T" refers to temperature of medium.
