the equilibrium will shift
rate of forward reaction will increase
rate of backward reaction will increase
rates of forward and backward reaction are not affected
Correct answer is C
Given: The equation below
A\(_{(s)}\) + 2B\(_{(g)}\) → 2C\(_{(aq)}\) + D\(_{(g)}\)
According to Le Chatelier's Principle:
Pressure changes affects only the gaseous reactants and products
There must be different amount of gaseous particles on both sides.
Generally; a decrease in the pressure shifts the equilibrium position in favor of the side with larger volume of gases.
I.e rates of backward reaction.

150°C
177°C
75°C
120°C
Correct answer is A
Parameters given:
V\(_1\) = 200 cm\(^3\); T\(_1\) = 27 + 273 = 300K.
V\(_2\) = 150 cm\(^3\); T\(_2\) = ?
P\(_2\) = 2P\(_1\).
Using the Ideal Gas Equation:
\(\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}\)
\(\frac{P_1 \times 200}{300} = \frac{2P_1 \times 150}{T_2}\)
\(\frac{2}{3} = \frac{300}{T_2}\)
T\(_2\) = 450K.
= 450K - 273K
= 177°C
177 - 27 = 150
That is the amount by which T1 must be increased.
