The gaseous reaction A + B hArr2C + D, +...

The gaseous reaction `A + B hArr2C + D, + Q `is most favoured at

A

High temperature and low pressure

B

Loww temperature and low pressure

C

Low temperature and high pressure

D

High temperature and high pressure

Text Solution

Verified by Experts

The correct Answer is:
B
`A(g)+B(g) hArr 2C(g)+D(g) +q`
The forward reaction is exothermic and proceeds with an increase in number of moles of gaseous components. Therefore, low temperature and low pressure will favour the forward reaction.
