1.	A catalyst alters the rate of a reaction by leading of increasing the energy of activation, In Heterogeneus catalysis adrosption mechanism occurs and Hemogeneus. Catalysis intermediate formation occurs. In auto catalysis one of the products acts on catalyst. The DeltaH of a reaction A + B to C is d-20 KJ mol^(-1). When a catalyst is used. What is DeltaH for the reaction without catalyst (magnitude)
Answer» `lt 20 KJ` `gt 20 KJ ` `20 KJ ` Depends on CATALYST SOLUTION :Catalyst does not change `DELTAH` of the reaction
