Question

Of the following which change will shift the reaction towards the product?
$I_2\left(g\right)\rightleftharpoons 2I\left(g\right),△H_r^0\left(298K\right)=+150kJ$

• A. Increase in concentration of $I_2$
• B. Decrease in concentration of $I_2$
• C. Increase in temperature
• D. Increase in total pressure

Answer 1

Answer: (A), (C)

The correct options are
A Increase in concentration of $I_2$
C Increase in temperature

The given reaction is endothermic. If we increase the temp. forward reaction will be promoted so that heat is absorbed to decrease the temp.
