Dear Abhinav

$\frac{k_T_2}{k_T_1}=\mu ^\frac{{T_2-T_1}}{10} =\mu ^{\frac{\Delta T}{10}}$

= 2^(90/10)

= 2^9

now you can simply find the increase in rate of reaction

Temperature coefficient is defined as change in rate ratio by an increase in 10^{o}C.

Mathematically, Temperature coefficient = \frac{k_{t+10^{o}}}{k_{t}}

Therefore, in the given situation we can conclude that when temperature changes from 30^{o}C to 40^{o}C then it is given that temperature coefficient is 2.

Hence, when temperature changes from 30^{o}C to 100^{o}C then rate of reaction will be 2^{7} which is equal to 128.

In the reaction A + 2B ⇌ 2C, if 2 moles of A, 3 moles of B and 2 moles of C are placed in a 2 L flask and
the equilibrium concentration of C is 0.5 mol/L. The equilibrium constant (KC) for the reaction is.....and please tell how you know that the reaction is going forward .. imean how to calculate the reaction quotient ???
