Question 142 of 246

For the given reaction,

2A(s) + B(g) C(g) + 2D(s) + E(s)

the degree of dissociation of B was found to be 20% at 300 K and 24% at 500K. The rate of backward reaction.

(1) increases with increase in pressure and temperature

(2) increases with increase in pressure and decrease in temperature

(3) depends on temperature only and decrease with increase in temperature

(4) increases with increase in concentration of B and increase in the temperature
