The reaction L â M is started with 10 g of L. After 30 and 90 min

1.	The reaction L â M is started with 10 g of L. After 30 and 90 minute, 5g and 1.25respectively. The order of reaction isa) 0b) 2c) 1d) 3
Answer» Option cReaction occurs as follows, L ---> M Initially L was 10 gram In 30 minutes it decreases to 5 gram i.e.50% In 60 minutes it decreases to 2.5 gram i.e.25% In 90 minutes it decreases to 1.25 gram i.e.12.5% We observe uniform decrease in reactant here, Hence this is a first order reaction.

Answer»

Option cReaction occurs as follows,

L ---> M

Initially L was 10 gram

In 30 minutes it decreases to 5 gram i.e.50%

In 60 minutes it decreases to 2.5 gram i.e.25%

In 90 minutes it decreases to 1.25 gram i.e.12.5%

We observe uniform decrease in reactant here, Hence this is a first order reaction.
