Answer: C) The concentration of HI will increase as the system approaches equilibrium.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression for is written as:
Thus as , the reaction will shift towards the right i.e. towards the product side.
Answer: The given statement is true.
Explanation:
A catalyst is defined as the substance that lowers the activation energy of a chemical reaction without itself getting consumed so that there will be increase in rate of reaction.
As catalyst lowers the activation energy so, reactant molecules with lower energy also participates in the reaction. Hence, more collisions occur due to which there is rapid formation of products take place through another path.
Therefore, we can conclude that the statement a catalyst increases the rate of a reaction without being consumed. It accomplishes this by providing another mechanism that has a lower activation energy, is true.
