Practice NSC / Matric Chemical Equilibrium in the app →When is a reversible reaction said to be at chemical equilibrium?Which kind of system lets energy move in and out but keeps all its matter inside?A mixture at equilibrium is heated. Which of the two reactions is then favoured?Nitrogen and hydrogen react to form ammonia, with four molecules of gas becoming two. The pressure on the equiA catalyst is added to a mixture that has already reached equilibrium. What is the effect on the equilibrium pFor the reaction A(g) plus B(g) forming 2C(g), a 2 dm cubed vessel at equilibrium holds 0.40 mol of A, 0.20 mo
